If an angle is x, the complement is

• x

• 90-x

• 180-x

If an angle is x, the supplement is

• x

• 90-x

• 180-x

CCSS.7.G.B.5

What is a correct equation for: "The measure of the supplement of angle x is 40 degrees larger than twice the measure of the complement."

• 180-x = 2(90-x) + 40

• 180-x = 2(90-x) - 40

• 2(180-x) + 40 = 90-x

What is a correct equation for "Two angles are supplementary. 4 times one angle is 2 time the other angle."

• 4x = 2(90-x)

• 4x = 2(180-x)

• 2x = 4(90-x)

What is a correct equation for "Three times the complement of an angle is 15 less than its supplement."

• 3(90-x) = 180 - x -15

• 90 - x = 3(180-x) - 15

• 90 - x - 15 = 3(180 - x)

What theorem is shown?

• If two <'s are supp to the same angle, they are $\cong$ .

• If two <'s are supp to $\cong$ <'s, they are $\cong$ .

• If two <'s are comp to the same angle, they are $\cong$ .

• If two <'s are comp to $\cong$ <'s, they are $\cong$ .
