Question

Find the measure of x, the missing angle shown below.

Answer 1

Since the internal angle of a triangle is = 180 degrees,

180 = 90 + 57 + x
x = 180 - 90 - 57
= 33

Answer 2

x=33

Explanation:

`\hookrightarrow \: x + 90 + 57 = 180(sum \: of \: all \: angles \: of \: triangle)\\ \hookrightarrow \: x = 180 - 90 - 57 \\ \hookrightarrow \: x = 33`
