A ski run is 1200 yards long with a vertical drop of 308 yards. Find the angle of depression from the top of the ski run to the bottom.

The vertical drop created an angle of 90 degrees.

Therefore, you have a right triangle.

Let's name the ski run AB, and the vertical drop BC.

Angle B would be 90 degrees.

We have two measurements AB = 1200 and BC = 308 so we can find the third measurement AC by doing pythagoras:

1200^2 + 308^2 = 1239 yards

now with the sine law

1239/sin90 = 308/sin(angle of depression)

angle of depression = sin-1(308 x sin90/ 1239) = 14.4 degrees

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
