Question

Hey! pls help me with this question on angles. would really be appreciated. have a nice day.

Answer 1

Using supplementary angles, it is found that the measures of the angles are given as follows:

• m<a = 30º.

• m<b = 90º.

What are supplementary angles?

Supplementary angles are two angles whose sum is of 180º.

An interior angle is supplementary with it's exterior angle, hence:

m<a + 150º = 180º -> m<a = 30º.

The sum of the three interior angles of a triangle is of 180º, hence:

30º + m<b + 60º = 180º

90º + m<b = 180º

m<b = 90º.
