Question

will he return?
9. (i) Find the measures of the angles of ∆PQR if its angles are
in the ratio 1:3:5.​

Answer 1

Answer:

let the angles be x, 3x and 5x respectively.

A.T.T.Q

x+3x+5x=180°

9x=180°

x=180°/9

x=20°

therefore, 1st angle=x=20°

2nd angle=3x=3×20=60°

3rd angle =5x=5×20=100°

hey friend, here is your answer.
