Question

I'm rather stuck on this question

Answer 1

Answer:

m<a = 30°

m<b = 90°

m<c = 60°

Step-by-step explanation:

Angles a, b, and c are all angles on a straight line.

Angles on a straight line add up to 180°.

Therefore, a + b + c = 180°

Given that a:b:c = 1:3:2, the measure of each can be calculated as follows:

Measure of each angle = the ratio proportion of that angle ÷ total ratio proportion * 180°

m<a = $\frac{1}{6} * 180 = 30$

m<b = $\frac{3}{6} * 180 = 90$

m<c = $\frac{2}{6} * 180 = 60$
