Question

answer with step by step for 7th​

Answer 1

Answer:

angle x = angle y-----(vertically opposite angle)--(1)

angle A=50°

Angle x=?

angle y=?

the sum of the all angles of a triangle is 180 degree

angle A+Angle x+angle y =180°

50°+angle x +angle x = 180°-----(from equation 1)

50° +2 angle x = 180°

2 angle x=180°- 50°

=130°

angle x=130/2

x =65°

The value of x is 65°
