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 Brainly. Have a wonderful day! :)
