Question

Three angles of a quadrilateral are of the Same measure and the measure of the fourth angles is 105°.find the measure of each of the equal angle?​

Answer 1

Answer:

let the three same measure angels be X

so,

X+X+X+105=360

3X=360-105

3X=255

X=255/3

X=85

therefore,

measure of angel A ,B ,C is 85
