To find X and Y X is horizontal Y is vertical, so that means SCP is horizontal and EF or a B is oops sorry all the way around
This problem exercises the concept of "similar triangles."
With similar triangles, we can compare the sides using ratios.
The equation we can use to find side A is stated below.
Side 1A / Side 1B = Side 2A / Side 2B
The number refers to the triangle, and the letter refers to the side of each triangle. Side A in both triangles must be the base of the triangle, and side B in both triangles can be either of the other sides. The only restriction is that once we pick a side B on triangle 1, we must pick that same side on triangle 2.
A / 7 = 3 / 2
Then we can solve for the length of side A.
A = 7*3/2 = 21/2 = (E) None of These
each gift =$10
total=y
number of gifts =x
therefore,total= each gift * number of gifts
=$10* x
