Question

5) The angles of a triangle is the ratio 3: 4. Find the measure of each angle.
​

Answer 1

Step-by-step explanation:

Angles are in the ratio of 3:4:5

Angles are in the ratio of 3:4:5Let the angles be 3x, 4x, 5x

5x∴3x+4x+5x=180 {Sum of the angles of triangle is 180°}

∴12x=180

∴12x=180∴x=15

∴12x=180∴x=15Hence, the angles are: 45°

60°, 75°
