The picture below shows a right-triangle-shaped charging stand for a gaming system: The side face of a charging stand is a right triangle labeled ABC. The measure of angle ACB is 90 degrees and the measure of angle ABC is 50 degrees. Side B C measures 3 inches. Which expression shows the height, AC, of the charging stand? 3 divided by cos 50 degrees 3 tan 50° 3 divided by tan 50 degrees 3 cos 50°

Vocaloid:

notice you are given the angle, and the adjacent side, then asked to find the opposite side which trig ratio (sin, cos, or tan) involves the adjacent and opposite sides?

chrishtiian:

would it be COS?

chrishtiian:

wait no, TAN

Vocaloid:

good, tan so tan = opposite/adjacent plugging in the values gives us tan(50) = AC/3 solve for AC

Would it be 25.17298894 so I would round that to 25.17?

Vocaloid:

notice how the answer choices are given in terms of the trig ratios so you don't need to use a calculator to figure out the decimal value tan(50) = AC/3 you just need to multiply both sides by 3 and then see which answer choice matches

so B. 3 tan 50°?

Vocaloid:

good

chrishtiian:

because you would multiply them to move the 30 to the other side
