A television camera at ground level is filming the lift-off of a space shuttle at a point 750 meters from the launch pad. Find the angle of elevation to the shuttle when the height of the shuttle is 300 meters.

theta=21.8014

Step-by-step explanation:

We want to find theta

Since this is a right triangle, we can use trig functions

tan theta = opp /adj

tan theta = 300/750

Taking the inverse tan of each side

tan^-1(tan theta) = tan^-1(300/750)

theta=21.8014

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
