Question

The measures of the angles of a triangle are shown in the figure below. Solve for x.

Answer 1

54

Explanation:

The angles of a triangle always add up to 180°, so you can add up the angles you do know, and subtract 180.

So in this case, you would do
`36+90=126`, then
`180-126=54`.

Answer 2

36+90+x= 180°

126+x=180°

x= 180 - 126

x= 54°
