Question

he angles of a quadrilateral are in A.P and their common difference is 15°, find the angle​

Answer 1

Answer:

angles are 67.5, 82.5, 97.5, 112.5

Step-by-step explanation:

sum of angles are s= 360

having 4 angles...n=4

360 = 2[ 2a+3(15)]

360= 4a + 90

4a= 270

a= 67.5

A2=82.5

A3 = 97.5

A4 = 112.5

:. angles are 67.5, 82.5, 97.5, 112.5
