Answer:
36° and 54°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the parts of the ratio, 4 + 10 + 6 = 20 parts
Divide 180 by 20 to find the value of one part of the ratio
180° ÷20 = 9° ← value of 1 part of the ratio
4 parts = 4 × 9° = 36°
10 parts = 10 × 9° = 90°
6 parts = 6 × 9° = 54°
