A campsite is 12.88 miles from a point directly below Mt. Adams. If the angle of elevation is 15.5° from the camp to the top of

nata0808 [166]

Answer:

3.57 miles

Step-by-step explanation:

Please consider the attachment.

We have been given that a campsite is 12.88 miles from a point directly below Mt. Adams. The angle of elevation is 15.5° from the camp to the top of the mountain. We are asked to find the height of the mountain.

We can see from the attachment that h is opposite side to angle 15.5 degrees and 12.88 miles in adjacent side.

We know that tangent relates opposite side of right triangle with its adjacent side.

$\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}$

$\text{tan}(15.5^{\circ})=\frac{h}{12.88}$

$\text{tan}(15.5^{\circ})\cdot(12.88)=\frac{h}{12.88}\cdot(12.88)$

$12.88\cdot\text{tan}(15.5^{\circ})=h$

$h=12.88\cdot\text{tan}(15.5^{\circ})$

$h=12.88\cdot(0.27732454406)$

$h=3.5719401274928$

$h\approx 3.57$

Therefore, the mountain is approximately 3.57 miles high.

48 miles per hour! Just double 30 minutes to get an hour, and double 24 as well which equals 48.
