Question

In the given figure, A = 40°, 3 = 60° and PQ
is parallel to AB. Find the other angles mentioned
in the figure​

Answer 1

Step-by-step explanation:

• In this figure PO||AB

So

Angle (1) = Angle A { Alternate angle }

Angle (3) = Angle B. { Alternate angle }

~ GIVEN THAT ~

A = 40°

3 = 60°

So

A = 1 = 40°

B = 3 = 60°

Now In triangle ∆ABC

A + B + 2 = 180 °

40° + 60° + 2 = 180 °

2 = 80°
