Question

The measure of 3 exterior angles of a quadrilateral are given. Find the measure of the fourth angle. Identify which of the following are concave quadrilateral.
29° ,84° ,113°​

Answer 1

Answer:

134°

Step-by-step explanation:

29 + 84 + 113

Let the fourth angle be x

then,

29 + 84 + 113 + x = 360

226 + x = 360

x = 360 ― 226

x = 134°

so, fourth angle be = 134°

Answer 2

Answer:

134°

29+84+113

let the fourth angle be x

then,

29+84+113+×=360

226+×=360

x=360-226

x=134°

so,fourth angle be=134°
