This is a problem that uses the tangent function as x is opposite the given angle and 15 is adjacent to it.

tan 27° = x/15

Multiply both sides by 15:

15 tan 27° = x

Solve:

x = 7.643

Triangle XYZ is reflected across the y-axis, and X = (4,-5). What are the coordinates of X’ ?
adelina 88 [10]
The correct answer is B.

You can come to this decision by picturing the initial point in your mind. Point X has a positive x-value and a negative y-value. This puts it in quadrant 2 on the coordinate plane. Now, if you flip that point over the y-axis, that makes its new location in quadrant three. In quadrant three, both the x and y coordinates are negative. So, the value wouldn’t change but both would become negatives.

I hope this helps. :)
