The radius of the circle of the area of ∆ abc is 84cm 2​

Answer»

Answer:

please mark me as brainlist

Step-by-step explanation:

Given: AREA of ∆ABC = 84 cm2

PB = 8 cm

PA = 6 cm

AB = 14 cm

BQ = 8 cm (Common tangent with PB)

AR = 6 cm (Common tangent with PA)

Since QC & CR are Common tangent

Let QC = CR = x

AC = 6 + x

BC = 8 + x

So ΔROA and ΔPOA are congruent

ΔPOB and ΔQOB are congruent

ΔQOC and ΔROC are congruent

Area of ΔROA = ΔPOA = 12 cm2

Area of ΔPOB = ΔQOB = 16 cm2

Area of ΔQOC = ΔROC = 2x

The SUM areas of all the small triangles = Area of ∆ABC

⇒ 2 × 12 + 2 × 16 + 2 × 2x = 84

⇒ 4x = 28

⇒ x = 7 cm

Answer: Length of AC = 13 cm & Length of BC = 15 cm

In a single throw of two dice , what is the possiblity that the sum is 9.​

Answer»

Answer:

1/9

Step-by-step explanation:

SAMPLE SPACE =

{ (1,1), (1,2), (1,3) , (1,4), (1,5), (1,6)

{ (2,1), (2,2), (2,3) , (2,4), (2,5), (2,6)

{ (3,1), (3,2), (3,3) , (3,4), (3,5), (3,6)

{ (4.1), (4,2), (4,3) , (4,4), (4,5), (4,6)

{ (5,1), (5,2), (5,3) , (5,4), (5,5), (5,6)

{ (6,1), (6,2), (6,3) , (6,4), (6,5), (6,6) }

Total number of sample space space = n(s) = 36

Let A be the event of getting sum of 9.

FAVOURABLE OUTCOMES of A = {(3,6), (4,5), (5,4), (6,3)}

Number of favourable outcomes of A = n(A) = 4

Probability or possibility = n(A)/n(s) = 4/36 = 1/9

The diagonal of cuboid r l=8,b=4,h=20​

Answer»

Answer :

  • Diagonal of cuboid is 21.9

Given :

To FIND :

  • Diagonal of cuboid

Solution :

As we know that,

  • Diagonal of cuboid = L² + b² + h²

Where,

  • l is length
  • b is breadth
  • h is height

》Diagonal of cuboid = √l² + b² + h²

》√(8)² + (4)² + (20)²

》√64 + 16 + 400

》√280

》21.9

Hence , Diagonal of cuboid is 21.9

More Explanation :

  • Lateral surface area of cuboid = 2h(l + b)
  • Total surface area of cuboid = 2(lb + bh + lh)
  • Volume of cuboid = lbh
  • Where , l is length , b is breadth and h is height

Jack spent of 1/3 her money on a pack of pens 1/2 of her money on a pack of markers and 1/8 of her money on a pack of pencils. what fractions of her money is left.​

Answer»

The fraction of the amount of money that Jing had left is  

The fraction of the amount of money Jing spent on the PACK of pens =  

The fraction of the amount of money she spent on a pack of marker =  

The fraction of the amount of money she spent on a pack of pencils =  

The fraction of the money left = 1

Further Explanation

One way to determine the total fraction of the amount of money she spent  = the fraction of the money left - the fraction of the amount she spent on pack of pens + fraction of the amount spent on marker + fraction of the money she spent on pencils

Firstly, WITHOUT the fraction of the money left, we have:

=  +  +  

=  +  + , it ALSO the same as

= (8+12+3) / 24 (24 is the lowest common denominator)

=  

Since the fraction of the money left = 1

Therefore we have:

= 1 –  

= (24 x 1) – (23 x 1) / 24 (24 is the smallest number that can divide the denominators)

Therefore we have:

= 24 – 23 / 24

= .

Therefore the fraction of the amount that Jing has left is .

Notably, we solve this question using the BODMAS rule.

Step-by-step explanation:

(1) 5.3 cm

Steps of construction:

1. Draw line segment AB = 5.3 cm.

2. With A as centre and radius more than half of AB, mark two arcs, one above and other below the line AB.

3. With B as centre and same radius, draw two arcs cutting the previous DRAWN arcs and name the point of INTERSECTION as X and Y.

4. Join XY and name the point where this line cuts AB as point P.

XY is the PERPENDICULAR bisector of AB.

Find the total surface area of a cuboid with dimensions 10cm,6cm and 4cm​

Answer»

\bf \: \underline{ Given} :

\sf \implies Breadth = 6 \: cm

\sf \implies Height = 8 \: cm

\bf \: \underline{To \: find} :

\sf \implies Total \: surface \: area \: of \: cuboid.

\bf \:  \underline{Formula \:  to \:  be  \: used},

\boxed{ \sf \: Total \: surface \: area \: of \: cuboid = \red{2(LB +BH + HL)}\: Sq.unit}

\sf \: Where,

\sf \bull \: \implies \:B = Breadth

\sf \bull \: \implies \:H = Height

\sf \: Therefore,

\sf \: \underline{Putting \: the \: values} \: :
