7 0

<span>1/3(21−3a)=6−a
distribute 1/3 to all factors in the parenthesis
7 - a = 6 - a
add "a" to both sides
7 = 6
This is not true, there are NO solutions to this equation...</span>

The angle of elevation to the top of a water tower from point A on the ground is 19.9°. From point B, 50.0 feet closer to the to

zepelin [54]

Answer:

Answer in terms of a trigonometric function :

$h = \frac{20tan(19.9)}{0.4-tan(19.9)}$

Answer in figures

$h = 190.5 feet$

Step-by-step explanation:

Consider the sketch attached below to better understand the problem.

Let x be the distance between point B and the base of the water tower.

$tan (19.9)=\frac{h}{50+x} ---------------equation 1\\$

$tan (21.8)=\frac{h}{x}----------------equation 2$

From equation 2,

$x =\frac{h}{tan21.8}=\frac{h}{0.4}$

substituting the value of x into equation 1, we get

$tan (19.9)=\frac{h}{50+(\frac{h}{0.4} )}$

$tan 19.9=h\times \frac{0.4}{20+h}$

cross multiplying,

$20\times tan(19.9) +htan(19.9)=0.4h$

$20tan(19.9)= h(0.4-tan(19.9))$

$h= \frac{20tan (19.9)}{0.4-tan (19.9)}$

The height of the tower is $h= \frac{20tan (19.9)}{0.4-tan (19.9)}$ in terms of the trig function "Tan"

The equation can simply be evaluated to get the answer in figures since the angles are given in the question

A 15-foot flag pole is next to a tree. The flag pole is casting a shadow of 22.5 feet and the tree is casting a shadow that is 1

muminat

Answer:32.1428571429 feet

Step-by-step explanation:

The flag is 15 feet.

It's shadow is 10.5 feet.

15/10.5=1.4285714286.

So the flag is above mentioned times of the shadow.

And the tree's hight will be,

22.5*1.4285714286

=32.1428571429 feet.
