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:

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
