Well really it would have to depend on the flashlight. Is it an led bulb or a regular bulb?
Here, I've attached a picture of the triangle that accompanies this explanation.
cot = = =
Now view the triangle.
PS. Angle theta will have a coordinate of (-, +) because it is in quadrant II.
sin of the angle would be opposite/hypotenuse, so sin =
cos of the angle would be adjacent/hypotenuse, so cos =
tan of the angle would be opposite/adjacent, so tan =
6 and -3
6 + -3 = 3
6 x -3 = -18
Hope that helps!
