Question

The measures of the angles of a triangle are in the ratio 5:6:7. What is the number of degrees in the largest of these angles?

Answer 1

The sum of interior angles of triangle is 180⁰

sum of ratios 5+6+7=18

first angle 5/18 X 180⁰=50⁰

second angle 6/18 X 180⁰ = 60⁰

Third angle 7/18 X180⁰ = 70⁰

the largest angle is 70 degree
