Question

6. In the given figure the value of x is
A

​

Answer 1

Angle a = 180°-125° = 55°

Value of x = 180°-60°+55°

= 180°-115°

= 65°

Answer 2

Answer:

The Exterior angle property of a triangle states that the sum of two interior opposite angles is the exterior angle.

x + 60° = 125° (Exterior Angle Property)

x = 125° - 60°

x = 65°

Hence, the value of ∠B is 65°
