Answer:
The unknown angle measures 56
Step-by-step explanation:
<u>Complementary Angles</u>:
Two angles are complementary when they add up to 90 degree.
An angle measure 34 less than a complementary angle. Which means angle one is 34 and angles two is 90 minus 34.
angle one + angle two = 90
34 + angle two = 90
angle two = 90 - 34
angle two = 56
