• 17.9

• 20.5

Solve for x. Round to the nearest tenth.

• 103.5

• 4.7

• 55.0

• 23.4

Set up the problem...

• sin X = 41/28

• tan X = 41/28

• cos X = 28/41

• sin X = 28/41

Set up the problem.

• sin(47) = x/28

• cos(47) = x/28

• tan(47) = x/28

• cos(47) = 28/x

What would you use to solve for a?

• sin

• cos

• tan

• Pythagorean theorem
