It is helpful to draw a figure.
Let represent the angle of elevation (the angle between the line of sight and the horizontal).
You can find by setting up the equation . To find you need to find .
(For the Level 1 Test, make sure your calculator is in degree mode.) To the nearest degree, the angle of elevation is .
