Given that the plane is at altitude of 1200m and the angle of depression is 28°, to calculate the distance between the the plane and the rock we assume that we a have right triangle whereby the distance of the plane form the ground is the height, the distance from plane to the rock is the hypotenuse and the remaining distance is the base:
thus
sin θ=opposite/hypotenuse
θ=28°
opposite=1200m
hypotenuse=h
thus
sin 28=1200/h
h=1200/sin 28
h=2556.065 m

Answer:
I'm stuck to.
Step-by-step explanation:
is there suppose to be an angle or a triangle?
To turn a decimal into a percent you simply multiply it by 100
to turn a percent into a decimal, you would remove the percent symbol and move the decimal point two place to the left (make sure you add zeros as needed)
hope this helps! :)
The answer is 3/10 but that’s not one of your options
