Question

# The three angles are in ratio 2:3:5 find the measure of each angle .classify the triangle

Solution

## Let common factor of ratio of angles is X. Ratios are 2:3:5 given. So, 2*X+3*X+5*x=180° — sum of three angles of a triangle. Now, 10*X=180° So, X=18°. Hence angles are 36° , 54° and 90°. It is a right triangle With two acute angles
