Question

In parallogram pqrs angle p:angle q 7:8 find all the angles

Answer 1

Answer:

adjacent ANGLES of parallelogram are supplementary ..

so,

let the common multiple be x.

7x + 8x = 180

15x = 180

x = 180 /15

x = 12

opposite sides of parallelogram are equal..

p = r = 7x = 7 × 12 = 84 degree

q = s = 8x = 8 × 12 = 96 degree..

IT WILL DEFINITELY HELP U....
