Question

in a cyclic quadrilateral PQRS if angle P - angleR=50degree then find measure of an angle P and angle R?​

Answer 1

Answer:

angle p plus angle r equals 180. That is equation 1

Angle p minus angle r equals 50. that is the 2 equation

now add the equations.

u will get p equals 115.

now r equals 180 minus 115 which is 65 degrees
