Functions (trigonometric)

Which is the ratio of the opposite leg to the hypotenuse in a right triangle?

• sine
• cosine
• tangent
• secant

Choose the correct ratio.

• cos(33)=x/14
• sin(33)=x/14
• cos(33)=14/x
• sin(33)=14/x

Choose the correct ratio you could use to solve for "x".

• sin(37)=x/14

• cos(37)=x/14

• tan(37)=x/14

• sin(37)=14/x
