A guy wire makes a 65° angle with the ground. walking out 37 feet further from the tower, the angle of elevation to the top of t

kicyunya [14]

Let's call the height of the tower $h$ and the distance from the 65 degree angle to the base of the tower $d$ .

We get two equations:

$\tan 65^\circ = \dfrac h d$

$\tan 39^\circ = \dfrac{h}{d+37}$

$h = d \tan 65^\circ = (d+37) \tan 39^\circ$

$d(\tan 65 - \tan 39) = 37 \tan 39$

$d = \dfrac{37 \tan 39}{\tan 65 - \tan 39}$

$h = d \tan 65 = \dfrac{37 \tan 39 \tan 65}{\tan 65 - \tan 39}$

$h \approx 48.1 \textrm{ feet}$

Answer:

21 of multiple choice and 17 of short answer questions

Step-by-step explanation:

Multiple choice = m
Short answer = s

Equations:

m + s = 38
2m + 3s = 93

Solve for s by eliminating m. Subtract the double of the first equation from the second one:

2m + 3s - 2(m + s) = 93 - 2(38)
3s - 2s = 93 - 76
s = 17

Find the value of m:

m = 38 - 17 = 21
