Answer:
90 degrees
Step-by-step explanation:
Step One: In order to solve this problem, you need to know that all angles in a triangle add up to 180 degrees.
Step Two: Now that we know that information, we need to add the angles we do know together: 34+56= 90 degrees.
Step Three: We subtract 90 from 180 to figure out the missing angles: 180-90= 90 degrees.
