Answer:

90 degrees, 120 degrees and 150 degrees

Explanation:

Given that three adjacent angles are at a point. The ratio of the measurements is 3:4:5. The angles should add to 360.

First add up all the ratio

3 + 4 + 5 = 12

For ratio 3

3/12 × 360 = 90 degree

For ratio 4

4/12 × 360 = 120 degree

For ratio 5

5/12 × 360 = 150 degree

90 + 120 + 150 = 360 degree.

The angles are therefore, 90 degrees, 120 degrees and 150 degrees
