Question

1) the measures of the angles of a triangle are in the ratio 5:6:7. find their measures.

solution :​

Answer 1

hey!! here is the solution of your question

sum of angles of triangle=180°

let take the angles be x

5x + 6x + 7x = 180°

18x = 180

x = 180÷18

x = 10

Therefore, the angles are:

5x= 5×10= 50°

6x= 6×10= 60°

7x= 7×10= 70°
