Answer:
90 degrees, 120 degrees and 150 degrees
Step-by-step 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
