Question

three angles of a quadrilateral are equal and the measure of fourth angle is 81°. what is the measure of each angle?

Answer 1

HEY MATE♡

HERE IS YOUR ANSWER:

Sum of all angles of a quadrilateral =360°

one angle=81°

let other be x.

according to the question

x+x+x+81=360

3x=360-81

3x=279

x=279/3

x=93

each angle is of 93°.

HOPE IT HELPED☆☆

Answer 2

let the 1s angle be x

so Angle 1=angle 2=angle 3=x

so

x+x+x+81°=360°

3x+81°=360°

3x=360-81

3x=279°

x=279÷3=93°

Therefore first 3 angles are equal to 93° .
