Question

Find the missing angle measurement for each triangle. (Round to the nearest whole degree)

Answer 1

45 degrees

Explanation:

there is 180 degrees in a triangle. the square in the corner means that is a 90 degree angle. Take 180 and subtract 90 and you get 90. the line in the other corner means that it is equal to the side opposite of it. So take 90 and divide by two and you get 45.
