Together, these two angles total 180°. Select the correct equation that is set up to solve for x.
100 - 2x = 180
180 - 2x = 100
180 = 2x
100 + 2x = 180
100 = 2x
Given that the two angles are supplementary (180°), choose the correct equation that is set up to solve for x.
180 + 2x = 54
54 + 2x = 180
54 = 2x
54 - 2x = 180
Given that the two angles are complementary (sum of the two angles is 90°), choose the correct equation that is set up to solve for x.
45 + 3x = 90
90 - 3x = 45
45 = 3x
45 + 90 = 3x
Given that the two angles are complementary (sum of the two angles is 90°), choose the correct equation that is set up to solve for x.
25 = 5x
90 = 5x
25 + 5x = 90
90 - 5 = x
Write an equation and solve for y.
y = 7
y = 263
y = 97
y = 83
Using the information you know about vertical angles, what is the value of x?
x = 97
x = 263
x = 7
x = 83
