For a person standing 100m from the center of the base of the excel tower, the angle of elevation to the top of the tower is 71.6 degrees. how tall is the effect tower

Given the statement: For a person standing 100 m from the center of the base of the excel tower, the angle of elevation to the top of the tower is 71.6 degrees.

Let h be the height of the Eiffel tower.

Angle of elevation is,

Distance of boy standing from the center of the base of the Eiffel tower is, 100 m.

Using tangent ratio:

From the given figure as shown;

Solve for h;

Multiply both sides by 100 we have;

or

Simplify:

therefore, the height of the Eiffel tower is, 300m

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

y -5 = (-1/4)(x + 8)
