Question

3. Find the values of x and y in each of the following figures:​

Answer 1

Answer:

since sides are same then x=y

now 180=150+z (assume z as third angle)

z=180-150=30

by angle sum property

x+y+z=180

2y+z=180

2y+30=180, 2y=180-30 = 150

y = 150/2 = 75

x=y=75

Answer 2

Step-by-step explanation:

it is an isosceles triangle

so x =180-115

x=65

then y

we know that

sum of interior angle =exterior angle

since x+y=115

65+y=115

y=115-65

y=5 0
