Question

state property of exterior angle a find the value of angle ABC , angle BCA if angle ABC is twice of angle BCA​

Answer 1

Answer:

Exterior Angle Property = The sum of interior opposite angles would be equal to the exterior angle.

∠BCA = x

∠ABC = 2x

2x + x = 105°

3x = 105°

x = 105°/3

x = 35°

∠BCA = 35°

∠ABC = 2 × 35°

= 70°
