Question

The measure of three angles of
quachilateral as e 65 83° and 104
find the measure of its
fourth angle:​

Answer 1

the angle sum property of a quadrilateral is 360

1st angle = 65

2nd angle= 83

3rd angle=104

let fourth angle be X

so.. 65+ 83 +104+X= 360

252+X = 360

X = 360-252

X= 108

hope it helps..
