${\huge{\underline{\underline{\sf{\blue{SOLUTION:-}}}}}}$

Question

⠀⠀⠀⠀• The sum of first two angles of a triangle is ⠀⠀⠀⠀⠀108° and the sum of the last two angles is

⠀⠀⠀⠀⠀132º Find the angles.

Answer

⠀⠀⠀⠀⠀•∠A= 48°

⠀⠀⠀⠀⠀• ∠B= 60°

⠀⠀⠀⠀⠀• ∠C = 72°

Given

⠀⠀⠀⠀• Sum of first two angles is 108°

⠀⠀⠀⠀• Sum of last two angles is 132°

To CALCULATE

⠀⠀⠀⠀• Angles __?

Step by step explanation

⠀⠀⠀⠀⠀

Let The angles of triangles be ∠A,∠B,∠C

∠A+∠B+∠C = 180° ( ${\sf{\red{Angle\: Sum \: Property}}}$ )

∠A+∠B= 108° ( ${\sf{\red{Given}}}$ )

PUTTING,

➫ 108° + ∠C = 180°

➫ ∠C= 180° - 108°

${\boxed{\blue{\tt{➫∠C= 72° }}}}$ ______________(1)

∠B+∠C= 132°

Putting value of C from eq 1

➫∠B+72°=132

➫ ∠B = 132-72

${\boxed{\blue{\tt{➫ ∠B= 60°}}}}$ ______________(2)

∠A+∠B= 108°( ${\sf{\red{Given}}}$ )

Putting value of B from eq 2

➫ ∠A+60°= 108°

➫ ∠A = 108°-60°

${\boxed{\blue{\tt{➫∠ A= 48°}}}}$

${\huge{\underline{\underline{\sf{\blue{Hence :-}}}}}}$

⠀⠀⠀⠀⠀•∠A= 48°

⠀⠀⠀⠀⠀• ∠B= 60°

⠀⠀⠀⠀⠀• ∠C = 72°

Findthe cost of putting a fence around it at rupee18find its perimeter.

Answer»

20. The area of a square is one side squared.

Let us consider:-

A side is x cm.

The GIVEN area is 128 cm².

This implies that:-

$\sf{\to x^2=128}$

$\sf{\to x=\sqrt{128}}$

$\sf{\to x=\sqrt{2^5}}$

$\sf{\therefore x=4\sqrt{2}}$ cm ...(1)

Here, the diagonal of a square is always x × √2.

$\sf{\therefore \sqrt{2} x=8}$ cm (ANSWER)

Here, the perimeter of a square is always 4x.

$\sf{\therefore 4x=16\sqrt{2} }$ cm (ANSWER)

21. The area of a square is one side squared.

Let us consider:-

A side is x m.

The given area is 80000 m².

This implies that:-

$\sf{\to x^2=80000}$

$\sf{\to x=\sqrt{80000} }$

$\sf{\to x=\sqrt{8\times 10^4}}$

$\sf{\to x=200\sqrt{2} }$ m

$\sf{\therefore x=\dfrac{\sqrt{2} }{5} }$ km ...(1)

Now

Here is the definition of speed.

$\sf{\to s=\dfrac{d}{t} }$ (here, km/h)

As per the question:-

$\sf{\to 4=\dfrac{\sqrt{2} }{5} \times \dfrac{1}{t} }$

$\sf{\to t=\dfrac{\sqrt{2} }{5\times 4}}$

$\sf{\therefore t=\dfrac{\sqrt{2} }{20} }$ HOURS (ANSWER)

22. Given that:-

(Cost):(FIELD)=1:9
The cost of putting the fence is 18.
The field is a square.

This results in insufficient information, because there is no area of field.

This problem cannot be solved. (ANSWER)

Extra Information

Such problems with insufficient information, cannot be solved.

For example:-

"A captain owns 26 SHEEP and 10 goats. How old is the captain?"

A physist does not memorize any formula. (Quora Answer)

For example, we used the definition.

$\sf{\to s=\dfrac{d}{t}}$

Formulas are derived from definitions, they don't need to memorize but basics.

The derivation would look like this:

$\sf{\to d=st\:\&\:t=\dfrac{d}{s} }$

Answer»

Answer:

$\bigstar{\bold{Option\:2:\:2.1\:cm}}$

Step-by-step EXPLANATION:

$\Large{\underline{\underline{\bf{Given:}}}}$

Height of cone(h) = 8.4 cm
Radius (r) = 2.1 cm

$\Large{\underline{\underline{\bf{To\:Find:}}}}$

Radius of the sphere

$\Large{\underline{\underline{\bf{Solution:}}}}$

→ FIRST we have to find the volume of the cone

→ Volume of the cone is given by the formula,

Volume of the cone = 1/3 × π × r² × h

→ Now we have to find the volume of the sphere

→ Volume of the sphere is given by

Volume of the sphere = 4/3 × π × R³

→ By given ,

Volume of cone = Volume of sphere

→ SUBSTITUTING the VALUES we get,

1/3 × π × r² × h = 4/3 × π × R³

→ Cancelling 1/3 and π on both sides,

r² h = 4 R³

→ Substituting the values,

2.1 × 2.1 × 8.4 = 4 R³

4 R³ = 37.044

R³ = 37.044/4

R³ = 9.261

R = ∛9.261

R = 2.1 cm

→ Hence the radius of the sphere is 2.1 cm

$\boxed{\bold{Radius=2.1\:cm}}$

→ Therefore option 2 is correct.

$\Large{\underline{\underline{\bf{Notes:}}}}$

→ Volume of a cone is given by,

Volume of a cone = 1/3 × π × r² × h

→ Volume of a sphere is given by

Volume of a sphere = 4/3 × π × r³

The side of the given figure of tangram is 8 unit long. If the top left vertex is placed on (3,4) such thatthe sides of the squares are parallel to X and y axis. Write the co-ordinates of each vertex and the points shown in the figure.

Answer»

GIVEN : side of the given figure of TANGRAM is 8 unit long . the top left vertex is placed on (3,4) such that the sides of the squares are parallel to X and y AXIS.

To find : coordinates of each vertex

Solution:

A is the top left vertex ( 3 , 4)

AB = 8

=> B = ( 11 , 4)

AD = 8

=> D = (3 , - 4)

C = ( 11 , - 4)

A ( 3 , 4) , B = ( 11 , 4) , C = ( 11 , - 4) and D = (3 , - 4)

G is mid point of AC

=> G = ( 7 , 0)

E is mid point of A & G

E = ( 5 , 2)

H is mid point of C & G

=> H = (9 , - 2)

F is mid point of A & D

=> F = ( 3 , 0)

I is 4 unit below E

=> I = ( 5 , -2 )

A ( 3 , 4) , B = ( 11 , 4) , C = ( 11 , - 4) , D = (3 , - 4) E = ( 5 , 2)

F = ( 3 , 0) G = ( 7 , 0) H = (9 , - 2) I = ( 5 , -2 )

The tip of her fishing rod is 1.8m above thesurfaceof the water and the fly at the end of the string rests on the water 3.6 m away and2.4 m from a point directly under the tip of the rod. Assuming that her string (fromthe tip of her rod to the fly) is taut, how much string does she have out (SeeFig. 7.235)? If she pulls the string at the rate of 5 cm per second, what will thehorizontal distance of the fly from her after 12 seconds .
Answer» Answer: 2.79m Step-by-step explanation: Let AB be the height of the TIP of the FISHING rod from the water surface. Let BC be the horizontal distance of the fly from the tip of the fishing rod. Then, AC is the length of the string. ∴ AC 2 =AB 2 +BC 2 [ By Pythagoras theorem ] ∴ AC 2 =(1.8) 2 +(2.4) 2 ∴ AC 2 =3.24+5.76 ∴ AC 2 =9 ∴ AC=3m Thus, the length of the string out is 3m She pulls the string at the rate of 5cm/s ∴ String pulled in 12 second = 12×5=60cm=0.6m Let the fly be at POINT D after 12 seconds. Length of string out after 12 second is AD. ⇒ AD = AC - String pulled by NAZIMA in 12 seconds. ⇒ AD=(3−0.6)m=2.4m ⇒ In △ADB, AB 2 +BD 2 =AD 2 (1.8) 2 +BD 2 =(2.4) 2 BD 2 =5.76−3.24 BD 2 =2.52 ∴ BD=1.587m Horizontal distance of fly =BD+1.2m Horizontal distance of fly =1.587m+1.2m ∴ Horizontal distance of fly =2.79m I hope you understand my so please please please please please please please please please please please please please please please please please please please please please please please please mark me as brainlest

Nazima is fly fishing in a stream. The tip of her fishing rod is 1.8m above thesurfaceof the water and the fly at the end of the string rests on the water 3.6 m away and2.4 m from a point directly under the tip of the rod. Assuming that her string (fromthe tip of her rod to the fly) is taut, how much string does she have out (SeeFig. 7.235)? If she pulls the string at the rate of 5 cm per second, what will thehorizontal distance of the fly from her after 12 seconds .

Answer»

Answer:

2.79m

Step-by-step explanation:

Let AB be the height of the TIP of the FISHING rod from the water surface.

Let BC be the horizontal distance of the fly from the tip of the fishing rod.

Then, AC is the length of the string.

∴ AC

2

=AB

2

+BC

2

[ By Pythagoras theorem ]

∴ AC

2

=(1.8)

2

+(2.4)

2

∴ AC

2

=3.24+5.76

∴ AC

2

=9

∴ AC=3m

Thus, the length of the string out is 3m

She pulls the string at the rate of 5cm/s

∴ String pulled in 12 second = 12×5=60cm=0.6m

Let the fly be at POINT D after 12 seconds.

Length of string out after 12 second is AD.

⇒ AD = AC - String pulled by NAZIMA in 12 seconds.

⇒ AD=(3−0.6)m=2.4m

⇒ In △ADB,

AB

=AD

+BD

2

=(2.4)

BD

2

=5.76−3.24

BD

2

=2.52

∴ BD=1.587m

Horizontal distance of fly =BD+1.2m

Horizontal distance of fly =1.587m+1.2m

∴ Horizontal distance of fly =2.79m
