Varvara68 [4.7K]

Answer:

The height of tower is 322.7 feet.

Step-by-step explanation:

Given

Distance between a building and tower= 250 feet

BCDE is a rectangle .Therefore, we have BC=ED and CD=BE=250 feet

In triangle ABE

$tan\theta=\frac{perpendicula \; side }{hypotenuse}$

$\theta=38^{\circ}$

$tan38^{\circ}=\frac{AB}{BE}$

$\frac{AB}{250}=0.781$

$AB=0.781\times250$

AB=195.25 feet

In triangle EDC

$\theta=27^{\circ}$

$tan27^{\circ}=\frac{ED}{CD}$

$\frac{ED}{250}=0.509$

$ED=250\times0.509$

ED=127.25 feet

ED=BC=127.25 feet

The height of tower=AB+BC

The height of tower=195.25+127.25=322.5 feet

The temperatures t, in burrtown starts at 32F asset midnight, when h=0. For the next few hours, the teampature drops 2 degrees e

defon

For this case, the first thing we must do is define variables.
We have then:
h: number of hours
t: temperature
We now write the equation that represents the problem.
We have then:
t (h) = -2h + 32
We note that for h = 0
t (0) = -2 (0) + 32
t (0) = 32
Answer:
An equation that represents the temperature, t, at your h is:
t (h) = -2h + 32
