Here, You need to apply "Proportionality Theorem"
According to this theorem, the ratio of components of a leg would be equal to the ratio of corresponding components of another leg.

In mathematical form,
TV/VS = TW/WU

Substitute their values,
14/6 = 21/(x+4)
14(x+4) = 21*6
14x+56 = 126
14x = 126-56
x = 70/14
x = 5

In short, Your Answer would be 5

Hope this helps!

Find Surface Area! WILL MARK BRANLIEST PLEASE HURRY!

Answer:

1164

Step-by-step explanation:

Surface area is the sum of the areas for all the faces. So 20×15= 300 since there is another one like that you multiply that answer by 2. Then 16×12= 192 then repeat and multiply 192 by 2. Then 12×15= 180 and since there is only one you dont multiply it by 2. Now add (192×2) + (300×2) + 192.

384 + 600 + 192 = 1164

Jane is using a carpenter’s square at eye level to determine the height of the tree, as shown in the figure. She is standing 9 f

larisa [96]

Applying the trigonometry ratio, TOA, the measurement that is closest to the height of the tree in feet is: D. 21

Recall:

Trigonometry ratios can be applied to solve any right triangle for missing side lengths or angles. They are denoted with the acronym, SOH CAH TOA.

Using trigonometry ratio, TOA, find the length of the side of the tree in the bigger triangle as follows:

tan 60 = x/9

x = tan 60 × 9

x = 15.6 ft

Height of the tree = 15.6 + 5.2 = 20.8 ft.
