Question

The angle of a triangle are in the ratio 2:3:5 determine the largest angle

Answer 1

Answer:

Let the angles be 2x, 3x, 5x respectively

ANGLE SUM PROPERTY

2x + 3x + 5x = 180

10x = 180

x = 18

Angles

2x = 36°

3x = 54°

5x = 90°

Hence, 5x is largest angle

Ratios are 2:3:5 given. So, 2*X+3*X+5*x=180° — sum of three angles of a triangle. So, X=18°. Hence angles are 36° , 54° and 90°.
