42°

Step-by-step explanation:

its 42° because its smaller than 48° and that's the only option smaller lol

42 degrees

Step-by-step explanation:

The angle forms a right angle, which in total would be 90 degrees.

48 + 42 would be the only option because it is the only one that adds up to 90 degrees.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
