Question

∠P : ∠Q : ∠R = 1 : 2 : 3 and altitude from P to QR is 4cm. Find the perimeter of
ΔPQR.

Answer 1

Answer:

angles according to ratios are

x + 2x + 3x = 180

6x =180

x = 30

so the angles are 30, 60, 90

and you can also find out the other side of the angles by using trignometric rule . once you find all the sides just add them

i dont have time now , thanks
