5 points
An airplane approaches an airport. At a certain time, the plane is 1020m
high. Its angle of elevation measured from the airport is 20.5 degrees.
How far is the plane from the airport to the nearest meter? *
A-2728
B-2913
C-1089
D-3

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

step-by-step explanation:

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
