If the measure of is 74°, what is the measure of ?

Well, you haven't submitted a photo of the problem, so it's going to be a bit tough to answer this question for you.

If the angle is a 180 degree (or strait) angle, you would do 180-74.
If the angle is a 90 degree (or right) angle, you would do 90-74.
If you are solving for a consecutive angle, I cannot give you the proper visual as to how to solve it. What I usually do is use the consecutive interior angle theorem to find my answer.

If you still need help, please provide a picture if possible of the problem you are working on. It would help us dearly as to how to help you get the answers you need.

Thank you for using . Have a wonderful day! :)
