Question

Find the value of the missing angle ``

180

50

90

Answer 1

50 because there can only be 1- 90 degrees angle in a triangle. A 180 angle is a strait line. You can go through a process of elimination

Answer 2

Answer:50

Explanation:

a right angle is always 90 degrees and we know triangles add to 180 degrees. So add 90 and 40 to get 130. Then subtract 180 from 130 to get 50.
