Answer 2

∠p = 22.5° , ∠q = 45° , ∠r = 112.5°  if the angle of a triangle pqr are in the ratio 1:2:5

Step-by-step explanation:

the angle of a triangle pqr are in the ratio 1:2:5

Let say Angle p  = A

then Angle q = 2A

& Angle r = 5A

Sum of angles of a triangle = 180°

∠p + ∠q + ∠r = 180°

=> A + 2A + 5A = 180°

=> 8A = 180°

=> A = 22.5°

2A = 45°    & 5A = 112.5°

∠p = 22.5°

∠q = 45°

∠r = 112.5°
