Isaac's camp is 5,280 feet from a point directly beneath Mt. Monadnock.
What is the height of the mountain if the angle of elevation is 25.27°.
Round the answer to two decimal places.
feet
Height of the mountain =
hiking distance=

Respuesta :

Step-by-step explanation:

The attached figure shows the whole scenerio.

BC = 5280 feet

We need to find height of the mountain. i.e. AB and the hiking distance i.e. AC.

Using trigonometry as follows :

[tex]\tan\theta=\dfrac{AB}{BC}\\\\AB=\tan(25.27)\times 5280\\\\AB=2492.46\ \text{feet}[/tex]

The height of the mountain is 2492.46 feet

Also,

[tex]\sin\theta=\dfrac{AB}{AC}\\\\AC=\dfrac{AB}{\sin\theta}\\\\AC=\dfrac{2492.46}{\sin(25.27)}\\\\AC=5838.72\ \text{feet}[/tex]

Hence, Height of the mountain =  2492.46 feet

hiking distance=  5838.72 feet.
