Question

Find the unknown angle measurement

Answer 1

65

Explanation:

115 + x = 180

x = 180 - 115

x = 65

Answer 2

65°

Explanation:

A right-angle equals 90°. Two right angles would be a line like shown in the picture.

So, 90 + 90 = 180.

Since we know the whole amount of the 2 angles combined is 180, all we have to do is subtract 115 from 180 to find the missing value.

180 - 115 = 65

Therefore, 65° equals x.
