Question

In the following figure L is a line, find 'a' and give reason

Answer 1

Please write the angle of left side.☺☺☺

Answer 2

Heya!!

According to question,

1st angle = a+50

2nd angle = a

Then,

By linear pair,

a+50 + a = 180°

=) 2a + 50° = 180°

=) 2a = 130 °

=) a = 130 / 2

=) a = 65

Hence, the value of a is 65°

Hope it helps uh.
