Look at the figure:
If tan xº = 3/Y and cos xº = Y/Z what is the value of sin xº?

which agrees with the first answer in your list of options.

Step-by-step explanation:

Recall that the tangent is defined as the quotient between the sin of the angle divided by the cosine of the same angle. Therefore for this case we have:

We also know that:

So we now replace this expression for the cosine in the foirst equation we analyzed:

d. vertex

step-by-step explanation:

it has the same slope and a different y-intercept

hope this : )
