Triangle ABC congruent to triangle DEF,angle a=30 degress angleb=80degress then find f

Answer»

Answer:

Here is your answer..

Given ∆ABC congruent to ∆DEF

By theorem 8.6 of similar triangles of class 10

Angle A=Angle = D

Angle B=Angle E

Angle C=Angle F

So, A+B+C=180

30+80+c = 180

110+c=180

C = 180-110=70.

9.	In the adjoining figure, sides BC, CA and AB of ABCTouch a circle at point D, E and F respectively.If BD = 4 cm, DC = 3 cm and CA = 8 cm, then the length ofSide AB is:
Answer» Given :- ∆ABC is a ∆. Circle Touches sides BC, CA and AB of ∆ABC Touch a circle at point D, E and F respectively. BD = 4cm. DC = 3CM. CA = 8cm. To Find :- Side AB ? . Solution :- Refer to Image First. Tangent Theoram :- States that if we draw two lines from the same point which lies outside a circle, such that both lines are tangent to the circle, then their lengths are the same. So, with Tangent Theoram we get :- → AF = AE → DC = CE → BD = BF . so, → BD = 4cm. (Given). → BF = 4cm. --------------- Equation (1). And, → DC = 3cm. (Given). So, → CE = 3cm. So, → AE = CA - CE → AE = 8 - 3 → AE = 5cm. So, → AF also = 5cm. ------------ Equation (2). Hence, From Equation (1) & (2), we get, → AB = AF + FB → AB = 5 + 4 → AB = 9cm. (Ans).

In the adjoining figure, sides BC, CA and AB of ABCTouch a circle at point D, E and F respectively.If BD = 4 cm, DC = 3 cm and CA = 8 cm, then the length ofSide AB is:

Answer»

Given :-

∆ABC is a ∆.
Circle Touches sides BC, CA and AB of ∆ABC
Touch a circle at point D, E and F respectively.
BD = 4cm.
DC = 3CM.
CA = 8cm.

To Find :-

Side AB ? .

Solution :-

Refer to Image First.

Tangent Theoram :- States that if we draw two lines from the same point which lies outside a circle, such that both lines are tangent to the circle, then their lengths are the same.

So, with Tangent Theoram we get :-

→ AF = AE

→ DC = CE

→ BD = BF .

so,

→ BD = 4cm. (Given).

→ BF = 4cm. --------------- Equation (1).

And,

→ DC = 3cm. (Given).

So,

→ CE = 3cm.

So,

→ AE = CA - CE

→ AE = 8 - 3

→ AE = 5cm.

So,

→ AF also = 5cm. ------------ Equation (2).

Hence, From Equation (1) & (2), we get,

→ AB = AF + FB

→ AB = 5 + 4

→ AB = 9cm. (Ans).

there is a loss of 25% on an article when it is sold at 3/5th the previous selling price. what is the actual profit% on it ?

Answer»

Answer:

Ans is 25%

Step-by-step EXPLANATION:

see there is a loss of 25% on a article

it MEANS its s.p is 75%the c.p

* the loss is occured when it is SOLD at 3/5 tghe the previous selling price

it means

down the selling price would be===profit%*cp+cp ----------use this in the PLACE of sp below

75/100* C.p= 3/5 S.p(previous selling price) ------------now SOLVE for sp

lets do

75/100*CP=3/5( (profit/100)*cp+cp )

75/100*CP=3/5 (100cp+x*cp)/100--------------by taking lcm x is profit %

75/100*cp=3/5 (cp(100+x)/100)---------taking cp as common

evaluate

(75/100)*cp/cp *100=3/5(100+x)

on solving we get x =25

33.	Solve for x and y 3x+y+1=0 and 2x-3y+8 =0
Answer» Step-by-step explanation: GIVEN - 3x + y + 1 = 0 2X - 3Y + 8 = 0 To Find - Value of x and y Now, 3x + y = - 1 2x - 3y = - 8 Using Substitution method, 3x + y = - 1 y = - 1 - 3x Substituting the value of y on 2x - 3y = - 8 = 2x - 3(- 1 - 3x) = - 8 = 2x + 3 + 9x = - 8 = 11x = - 8 - 3 = 11x = - 11 = x = -11/11 = x = - 1 Now, Substituting the value of x on 3x + y = - 1 = 3(- 1) + y = - 1 = - 3 + y = - 1 = y = - 1 + 3 = y = 2 Hence, The value of x is - 1 and The value of y is 2 Verification - Substituting the value of x and y on 3x + y = - 1 = 3(- 1) + 2 = - 1 = - 3 + 2 = - 1 = - 1 = - 1 LHS = RHS Now, Substituting the value of x and y on 2x - 3y = - 8 = 2(- 1) - 3(2) = - 8 = - 2 - 6 = - 8 = - 8 = - 8 LHS = RHS Hence, Verified..

33.

Solve for x and y 3x+y+1=0 and 2x-3y+8 =0

Answer»

Step-by-step explanation:

GIVEN -

3x + y + 1 = 0

2X - 3Y + 8 = 0

To Find -

Value of x and y

Now,

3x + y = - 1

2x - 3y = - 8

Using Substitution method,

3x + y = - 1

y = - 1 - 3x

Substituting the value of y on

2x - 3y = - 8

= 2x - 3(- 1 - 3x) = - 8

= 2x + 3 + 9x = - 8

= 11x = - 8 - 3

= 11x = - 11

= x = -11/11

= x = - 1

Now,

Substituting the value of x on

3x + y = - 1

= 3(- 1) + y = - 1

= - 3 + y = - 1

= y = - 1 + 3

= y = 2

Hence,

The value of x is - 1

and

The value of y is 2

Verification -

Substituting the value of x and y on 3x + y = - 1

= 3(- 1) + 2 = - 1

= - 3 + 2 = - 1

= - 1 = - 1

LHS = RHS

Now,

Substituting the value of x and y on 2x - 3y = - 8

= 2(- 1) - 3(2) = - 8

= - 2 - 6 = - 8

= - 8 = - 8

LHS = RHS

Hence,

Verified..

46.	IF 2-ROOT OF 3,THEN FIND THE VALUE OF X^2+1/X^2
Answer» Answer: As X= 2+30.5 then x - 1/x = 2+30.5 - 1/2+30.5 Then TAKE L.C.M. = [ (2+30.3)2+1 ] / 2+30.5 = [ 6+4root3] / 2+root3 Then RATIONALISE the Denomenator =[(6+4root3)(2-root3)] / [(2+root3)(2-root3)] =[12-6root3+8root3-12] / [4-3] = 2ROOT3 /1 Answer = 2root3

46.

IF 2-ROOT OF 3,THEN FIND THE VALUE OF X^2+1/X^2

Answer»

Answer:

As X= 2+30.5

then x - 1/x = 2+30.5 - 1/2+30.5

Then TAKE L.C.M.

= [ (2+30.3)2+1 ] / 2+30.5

= [ 6+4root3] / 2+root3

Then RATIONALISE the Denomenator

=[(6+4root3)(2-root3)] / [(2+root3)(2-root3)]

=[12-6root3+8root3-12] / [4-3]

= 2ROOT3 /1

Answer = 2root3
