Question

Find the angles value

Answer 1

Step-by-step explanation:

A = 40° ( Vertically opposite Angle)

B = ?

40 + b = 180

b = 180 - 40

b = 140°

as , interior angles on the same side of transversal are supplementary.

C = 40° ( Alternate Interior Angle )

d = 30 + 40 + 50

d = 120° ( corresponding angle )

hope this answer helps you dear....take care!
