Question

4. APQR is an isosceles triangle with PQ = QR. If angle Q = 50', what is the measure of angle R?​

Answer 1

Step-by-step explanation:

let the angle R is x degree

so triangle.is isosceles then angle R is equal to angle P

then

x+x+50=180

2x=130

x=65

so angle R is 65 degree

Answer 2

Step-by-step explanation:

R=50°

R=50°ACCORDING TO ISOCELES TRIANGLE THEOREM

R=50°ACCORDING TO ISOCELES TRIANGLE THEOREMIF TWO SIDES ARE CONGRUENT THEN THE ANGLES OPPOSITE TO THEM WILL ALSO BE CONGRUENT.
