Question

the measurment of two adjacent angles of a quadrilateral are 100° and 80° and the other two angle are equal. find the measure of each equal angle​

Answer 1

Answer:

90 degrees

Step-by-step explanation:

quadrilateral angle sum is 360

so 80+100+x+x(other 2 angles are equal so taking the 2 as x) we get

180+2x=360

2x=360-180

2x=180

x=180/2

x=90 degree
