Question

PQR is an isosceles triangle with PR = PQ.

(5x -4°
(x + 52)
Calculate the value of y.

Answer 1

Explanation:

As two sides are equal so angles opposite to these are also equal, hence

5x-4=x+52

4x=56

X=14

Now,

R=5x-4

R=66

And,Q=x+52

Q=66(we already knew both angles are equal)

Now as sum of all angles of triangle equal 180 so,

66+66+P=180

P=48
