Find the surface area of the tent model.
the height is 18, base is 14 on one side and the height of the base is 8.

answer choices:
a. 620.7 ft^2
b. 812 ft^2
c. 560 ft^2
d. 746.7 ft^2

step-by-step explanation:

the areas of two similar triangles are 18 cm2 and 8 cm2. one of the sides of the first triangle is 4.5 cm. what is the length of the corresponding side of the other triangle?

5x+10 is the correct one

hope this

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
