Question

the measure of two adjacent angle of a quadrilateral are 100 degree and 40 degree the remaining two angles are equal to each other find the measure of each angle of the angles

Answer 1

sum of all angles of a triangle is 360 degree
so, 100+40 +x+x = 360.
2x= 360- 140
2x = 220
x= 220/2=110 answer
hope helps

Answer 2

Answer:

sum of all angles of a triangle is 360 degree

so, 100+40 +x+x = 360.

2x= 360- 140
