Answer:
[see below]
Step-by-step explanation:
The triangle shown is a right triangle. I am assuming that the 'x' is the missing angle measurement.
The three angle measures in a triangle add up to 180 degrees.
[tex]60 + 90 = 150\\\\180 - 150 = 30[/tex]
The third angle should measure 30 degrees.
Hope this helps.
