Question

the angles in a quadrilateral are x ,(x+10),(x+20) and (2x-30)degrees find them​

Answer 1

Step-by-step explanation:

By angle sum property of quadriletral.

according to problem....

x+x+10+x+20+2x-30 = 360 degree

5x = 360 degree

x = 360/5

x= 72 degree

so angles are 1) 72 degree

2) 72+10=82degree

3)72+20= 92degree

4) 72×2-30 = 144 -30

= 114degree
