Question

34. The measures of four angles of a quadrilateral are (2x + 10). (3x+15)
(4x - 30)° and (2x - 20)º respectively. Then find the measure of the smallest exterior angle of it
the answer is 60 degree but how pls solve my question ​

Answer 1

Answer:

x=35

Step-by-step explanation:

sum of all angles of quadrilateral is 360

360=2x+10+3x+15+4x-30+2x-20

=11x-25

therefore, 360+25=11x

385=11x

x=35
