Question

The measures of the angles of a triangle are in the ratio of 5:6:7. What are the measures of the angles?

Answer 1

we know that sum of all angles of triangle is 180

let angles be 5x , 6x , 7x

now sum of angles : 5x + 6x + 7x = 18x = 180

therefore we got x : 10

therefore angles : 50 , 60 , 70
