I am bad at angles. can someone please help?

x=25

Step-by-step explanation:

a triangles angles total to 180

we know we have one right angle, thats 90 degrees taken

90 degrees r now left

we combine the x'es, so now we have 3x+15

after subtracting 15 from 90, we have 75

so  now our equation is 3x=75

75÷3=25

x=25

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.
