Jack uses angle relationships to design public structures, such as buildings, bridges, and streets. He designs walking paths in a park as shown below. What is the measurement of angle DMC? How do you know?

90 degrees

Step-by-step explanation:

Angle DMC is vertical angles with angle AMB. Vertical angles always have the same degree measure.

Since angle AMB = 90 degrees, we know that because DMC = AMB, then angle DMC is also 90 degrees.

Hope this helps!
