A person is standing 50 ft from a statue. The person looks up at an angle of elevation of 8 degrees when staring at the top of t

borishaifa [10]

The height of the statue is 19.5 feet.

Why?

We can solve the problem using trigonometric formulas. In this case, we are going to use the trigonometric formula of the tangent.

We know that the person is standing 50ft from the statue, so, it will be the base of the two triangles formed by both angles (elevation and depression)

Using the trignometric formula, we have:

First triangle:

$tg(\alpha )=\frac{h_{1}}{base} \\\\tg(8\°)=\frac{h_{1}}{50ft}\\\\0.14*50ft=h_1\\\\h_1=7ft$

Second triangle:

$tg(\alpha )=\frac{h_{2}}{base} \\\\tg(14\°)=\frac{h_{1}}{50ft}\\\\0.25*50ft=h_1\\\\h_1=12.5ft$

Now, the total height of the statue will be:

$TotalHeight=h_1+h_2=7ft+12.5ft\\\\TotalHeight=19.5ft$

Have a nice day!

Direct Variation. ¯\_(ツ)_/¯

Alekssandra [29.7K]

Answer:

y = 1/6

Step-by-step explanation:

direct variation

y =kx

substitute in what we know to find k

1/2 = k*3

solve for k

divide by 3

1/2 /3 = k

1/6 = k

substitute k into the direct variation equation

y = 1/6 x

let x = 1

y = 1/6 *1

y = 1/6

If the clock is held at a constant 0.0ºc over a period of 24 hours, how much longer or shorter does the clock measure compared t

NARA [144]

If the clock is held at a constant 0.0ºc over a period of 24 hours, the clock will be exactly the same as the perfect clock because it is at a constant 0.0 ºc for 24. Meaning there is no deviation on its reading

Maru [420]

Answer:

Renata has a home loan for $150,000 at 7.5% interest for 30 years and her payment is $987.00 per month.

I have solved this using excel sheet that is attached here.

p = $150000

r = 7.5%

t = $30\times12=360$

EMI = $987

You can see the excel sheet, after first month principle is $ 149,950.50 and after second month it is $149,900.69 .
