Question

In quadrilateral pqrs, aq and AR are the bisectors of angle q and angle r respectively, such that angle aqr =30 degree and angle arq =40 degree if angle qps =130 degree then find out angle psr
Pls pls answer fast

Answer 1

Answer: 90 degree

Step-by-step explanation:

Total addition of all 4 angles of a quadrilateral =360 deg.

angle p = 130 deg

angle q = 2 x angle aqr = 2 x 30 = 60 degree

angle r = 2 x angle arq = 2 x 40 = 80 deg

so sum of all above angles = 270 deg

angle psr = 360-270 = 90 deg
