Question

the measure of two adyncert angles of a quadrilateral
are 100 and 30° and the other two angles are equal
Find the measure of each equal angle​

Answer 1

Answer:

the measure of the two adjacent angles is 100° and 30°

Step-by-step explanation:

let the two remaining equal angles be 'x'

since the total of all angles of a quadrilateral is 360°

Therefore

100+30+x+x=360°

130+ 2x = 360°

2x=360-130

2x=230°

therfore x=230/2

x=115°
