Question

in ∆ PQR ; P=30° PQ =PR then find measurement is Q and R​

Answer 1

SOLUTION:

• It has been given that ,

PQ = PR

So,

It is an isosceles triangle ,

hence, angle Q = angle R.

Let it be x.

Now, we know that the sum of the angles of a triangle = 180°.

so,

angle P + angle Q + angle R =180°

30° + x + x = 180°

2x = 180° - 30°

x = 150°/2

x = 75°

HENCE, ANGLE Q = ANGLE R = 75°.
