Label Opposite Adjacent Hypotenuse

Find the value of the missing side of the triangle. Hint: Pythagorean Theorem. Make sure to draw/write down this triangle, you will continue to use it!

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

• a/c

• b/c

• c/a

What trig ratio would be used to solve for x?

• Sine

• Cosine

• Tangent

How would you set up an equation for x?

• sin 29 = 8/x

• sin 29 = x/8

What is the length of x?

• 7.43

• 4.59

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

• 12.37

• 24.29

• 0.034

• 29.24
