Alexxx [7]3 years ago
4 0

Let's solve for x using trigonometric relation ( Cos )

we know,

\cos(30 \degree)  =  \dfrac{base}{hypotenuse}  =   \dfrac{ \sqrt{3} }{2}

now

\dfrac{x}{8}  =  \dfrac{ \sqrt{3} }{2}

x =  8 \times \dfrac{ \sqrt{3} }{2}

x = 4 \sqrt{3}

hence, the value of x is 4 \sqrt{3}

A survey team is trying to estimate the height of a mountain above a level plain. From one point on the plain, they observe that
aliya0001 [1]

Answer:

5507.79 feet

Step-by-step explanation:

To find the height of the mountain, we can draw triangles as in the image attached.

Let's call the height of the mountain 'h', and the distance from the first point (31 degrees) to the mountain 'x'.

Then, we can use the tangent relation of the angles:

tan(34) = h/x

tan(31) = h/(x+1000)

tan(31) is equal to 0.6009, and tan(34) is equal to 0.6745, so:

h/x = 0.6745 -> x = h/0.6745

using this value of x in the second equation:

h/(x+1000) = 0.6009

h/(h/0.6745 + 1000) = 0.6009

h = 0.6009 * (h/0.6745 + 1000)

h = 0.8909*h + 600.9

0.1091h = 600.9

h = 600.9 / 0.1091 = 5507.79 feet
