Question

Marco is building a house. he bought lots of wood to make the frame of the house. he wants right angles for his corners. if he uses a piece of wood that is cut at a 55-degree angle, what must be the angle measure of the other piece of wood that he uses to complete the corner?

Answer 1

the other angle is adjacent to 55 degrees which means:

55+x=180

x=125 so it 125 degrees
