Question

A set of angles has a ratio of 5:2. If the larger angle measures 105o, then what is the measure of the smaller angle?

Answer 1

42°

Explanation:

The 5 part of the ratio represents 105°

divide 105 by 5 to find the value of one part of the ratio

`(105)/(5)` = 21° ← 1 part of the ratio, hence

2 parts = 2 × 21° = 42° ← smaller angle
