Answer:
30 degrees
90 degrees
60 degrees
Step-by-step explanation:
If two of the sides are four, we know that the triangle is a right triangle so one angle is 90 degrees. if the other angle is 30, you can add them. 30+90=120. Then subtract it by 180 because all angles in a triangle add up to 180. 180-120=60.
the answer is going to be -1
