Question: The angles of a triangle are in the ratio of 23:4. Find the measure of each

The angles of a triangle are in the ratio of 23:4. Find the measure of eachangle of the triangle.

Answer:

40° Angle 1

60° Angle 2

80° Angle 3

Explanation:

Total parts = 2+3+4

= 9

So, 180÷9 = 20

Therefore, one part is 20°

2 part = 2×20 = 40°

3 part = 3×20 = 60°

4 part = 4×20 = 80°
