Question

The interior angles of a quadilateral are (2x+15),(2x-5),(3x+75)and (3x-25).find the value of x.smallest interior angle of a quadilateral , the largest interior angle of a quadilateral and the largest exterior angle

Answer 1

Answer:

(2x+15)+(2x-5)+(3x+75)+(3x-25) = 360

(since sum of all interior angle of a quadrilateral= 360)

10x+60 = 360

10x =360 - 60

10x = 300

X=300/10

X=30
