2.Anita again missed the class of instruction on finding the unknown side lengths using trigonometric ratios. Teach her how to find the unknown length in the following example.
In the triangle ABC, angle A= 90, angle B=30 and BC=15, AB=8.

Segment xz is bisected by point y. if xy = 12x, and the measure of xz = 18x – 6, solve for x

Problem melissa is her dad build a walkway in their backyard. the walkway will be 54 feet long and 1.5 feet wide. the local hardware store sells tiles which are 1.5 by 1.5 feet and come in boxes of 12. how many boxes of tiles do they need?

Don't know how to find x given these segment lengths
