Answer 1

solution :-

shape BCD is an isosceles triangle meaning the base angles will be the same.

CA is a straight line meaning that it is 180 the sum of angles in a triangle always is 180

SO ,

180-36= 144

to find x you need to half 144 as it is the sum of the base angles of the isosceles triangle.

144/2= 72

x=72

the angle just below y is also 72. as CA is a straight line, 180-72= 108 giving you the answer for y

y=108

so to make the answer clear

x= 72

y= 108

i hope it's helpful for u ☺️

Answer 2

Area of ∆ABC = 36,

Area of ∆ABC = 36,Area of ∆PQR = 64

Area of ∆ABC = 36,Area of ∆PQR = 64AB = 12

Area of ∆ABC = 36,Area of ∆PQR = 64AB = 12The correspondence ABC ↔ PQR is a similarity.

Area of ∆ABC = 36,Area of ∆PQR = 64AB = 12The correspondence ABC ↔ PQR is a similarity.To find: PQ = ?

Area of ∆ABC = 36,Area of ∆PQR = 64AB = 12The correspondence ABC ↔ PQR is a similarity.To find: PQ = ?For this,

Recall the property,

Ratio of areas of two similar triangles = Ratio of squares of the corresponding sides

Area of ∆PQR / Area of ∆ABC =(PQ/AB)²

64 /36 = (PQ/AB)²

(PQ/AB) = √64 /36

(PQ/AB)= 8/6

PQ=AB ×8/6

PQ = 12×8/6

⇒ PQ = 2 × 8

⇒ PQ = 2 × 8⇒ PQ = 16

⇒ PQ = 2 × 8⇒ PQ = 16Thus, answer is 16.
