Understanding Quadrilaterals | Exercise 3.2

Question 1

Q1) Find x in the following figures.

(i)

(ii)

Solution 1:

(i): Since,

sum of all exterior angles of polygon is 360

Therefore,

125+125+x=360

250+x=360

x=360-250

x=110

(ii): Since,

sum of all exterior angles is 360 degrees,

Therefore,

90+60+70+x+90=360 (Linear pair theorum)

310+x=360

x=50
