Question

13. In the given figures, find x, y or 2 (whichever is required)​

Answer 1

Answer:

Fig. 9

Answer : x = 90°

Step-by-step explanation:

2nd isosceles triangle's —

we know that The opposite sides of two equal sides of two isosceles triangles are also equal.

so, The opposite of one of the two equal arms is = 50°

q = 50° and

Suppose one of the angles of the second isosceles triangle is = p

We know that the sum of the three angles of a triangle is = 180

so,

50 + 50 + p = 180

p = 180 - 100

p = 80°

so, 1st isosceles triangle's —

The opposite of two equal sides of the first isosceles triangle will be any shot = 40

so, x = 40° + 50° = 90°
