Question

Heyya cann anyone help me with this

Answer 1

a = 132°

Explanation:

this is a straight line and straight lines always measure up to 180°....so you subtract 48° from 180° and you get 132°

Answer 2

132°

Explanation:

We know that,

angles in a straight line are added upto 180°.

Accordingly,

`48 + a = 180`

Subtract 48 by both sides and make a the subject.

`a = 180 - 48 \\ a = 132 \degree`
