I have a straight angle. The angle measures 10x. What equation would I set up to find the value of x?

• x = 180

• 10x = 90

• 10x = 180

• 10 + x = 100

This straight angle was measured at 5y + 160 degrees. What equation would we use to find the value of y?

• 5y + 160 = 90

• 160 = 180

• 5y = 160

• 5y + 160 = 180

This straight angle was measured at 5y + 160 degrees. We can use the equation

5y + 160 = 180

Find the value of y

• y = 180

• y = 4

• y = 68

• y = 20

These two angles are supplementary (they combine to make a straight angle). One angle is 60 degrees, the other is 20x degrees. What equation could we set up if we want to solve for x?

• 20x + 60 = 90

• 20x = 60

• 20x + 60 = 180

• 80x = 180

These two angles are supplementary (they combine to make a straight angle). One angle is 60 degrees, the other is 20x degrees.

We can use the equation:

20x + 60 = 180

Solve for x

• x = 6

• x = 120

• x = 100

• x = 20

These two angles are supplementary (they combine to be a straight angle). All we know is that one angle is 4 times larger than the other angle. What equation could we use to figure out what y equals?

• 5y = 100

• y = 4y

• 4y + y = 180

• 4y + y = 90
