Question

please tell the answer​

Answer 1

Step-by-step explanation:

in first figure the exterior angle property should be used

exterior angle is equal to interior opposite angles

also the triangle is isosceles

therefore the angles at the base are equal therefore

x+x = 100°

2x= 100 °

x = 100/2

= 60°

in second figure due to exterior angle property

25 +35 = exterior angle

= 60°

60+60 = x (exterior angle property)

x= 120°
