Question

in a cyclic quadrilateral pqrs if angle p -angle r =50. then find angle p

Answer 1

In a cyclic quad
P+R = 180
P+50 = 180
P = 180-50
P = 139

Answer 2

Answer:

p=115

Step-by-step explanation:

by given condition

p+r=180

p=180-r

second condition

p-r=50

put p =180-r in p-r=50

180-r-r=50

130=2r

r=65

p=180-r

p=180-65

p=115
