Look at the 20°. Think about which side you would label opposite, adjacent and hypotenuse.

a) What side is labeled 10? b) What side is labeled r?

• adjacent, hypotenuse

• hypotenuse, adjacent

• opposite, hypotenuse

• opposite, adjacent

To solve for the hypotenuse in the last problem, this is the equation that would be used. What is the value of r?
