Question

in an isosceles triangle PQR, angle Q=angle R=2angle P. Find the three angles​

Answer 1

90 45 45 is the answer

Answer 2

Answer:

P=  90

Q= 45

R= 45

Step-by-step explanation:

∠Q = ∠R = ∠2P

Let 'x' be angle Q or R (Since they are equal)

We know that sum of three angle 180 degrees. i.e ∠P + ∠Q + ∠R = 180

1x (∠Q) + 1x (∠R) + 2x (∠P) = 180°

∴ 4x= 180

x= 180/4= 45°

So ∠Q= 1x= 1*45= 45°

∠R= 1x= 1*45= 45°

∠P= 2x= 45*2= 90°
