Sohcahtoa of X,Y

Which ratio represents the cos(θ)?

• x/y

• x/z

• y/x

• y/z

The side marked x is ​ (a)   to the angle that is 56 degrees. The side marked 20 is the ​ (b)   of the right triangle since it is across from the right angle. If we set up the ratio ​ x/20, we would be finding ​ (c)   56.

• opposite

• hypotenuse

• sin

• cos

• tan

• adjacent
