Question

A quadrilateral has 3 equal angles to 70 find the fourth angle​

Answer 1

If there are 3 angles of measure 70 degrees..

Therefore 3*70 = 210

360 - 210 = 150

Answer 2

aum of all angles in a quadilateral is 360°

3 of its angle measures is 70°

let the fourth angle be x°

then,

70+70+70+x=360

210°+x=360°

x=150°
