Answer 2

uphello frnd!

here's ur answer...

let the three equal Angles be x,x and x

we know that the sum of interior angle in a quadrilateral is 360°.

and one of the 4 angle is 150°

therefore x+x+x+150°=360°

→3x+150=360°

→3x=360-150

→3x=210

→x=210/3

→x=70°

hence the measure of each equal angle in the quadrilateral is 70°.

★ verification:-

=70°+70+°70°+150°

=140°+220°

=360°

hence verified.

thus the angles in the quadrilateral are 70°,70°,70° and 150°.

hope this helps..!
