A surveyor measures the angle of elevation of the top of a mountain from a point at
Sauron [17]

The height of the mountain from a point a sea level is approximately 1496.650 meters.

<h3>What is the height of mountain from sea level?</h3>

First, we construct the <em>geometric</em> diagram of the situation and find all needed angles and sides to determine the height of the mountain. First, we determine the missing side x by the law of sines:

Law of sines

1000 m/sin 3° = x/sin 14.261°

x ≈ 4706.886 m

Now we determine the height of the mountain by <em>trigonometric</em> functions:

h = 100 m + (4706.886 m) · sin 17.261°

h ≈ 1496.650 m

The height of the mountain from a point a sea level is approximately 1496.650 meters.

gogolik [260]

Let width be x

  • Length=x+8

\\ \rm\longmapsto 2(x+x+8)=48

\\ \rm\longmapsto 2x+8=24

\\ \rm\longmapsto 2x=24-8=16

\\ \rm\longmapsto x=\dfrac{16}{2}=8
