What is the missing angle measure?

33 degrees

Step-by-step explanation:

Because of the little square in the corner of the triangle, you know that that angle is 90 degrees. Since the second angle is 57 degrees and all of the interior angles of a triangle add up to 180 degrees, the final angle is 180-90-57=33 degrees. Hope this helps!

33

Step-by-step explanation:

the interior angle measure of all triangles is 180

you add the right and (90 degrees) to the 57 and subtract that from 180

this will get you 33
