Answer:
56 degrees
Step-by-step explanation:
Total angle measure of a triangle - 180 degrees
a square on an angle indicates that it is a right angle, or 90 degrees.
Another angle is 34 degrees.
<a + <b + <c = 180
Add them together then subtract them from the total angle measure (180)
90 + 34 + <c = 180
124 + <c = 180
124 - 124 + <c = 180 - 124
<c = 56
