The figure shows a person estimating the height of a tree by looking at the top of the tree with a mirror. Assuming that both the person and the tree form right angles with the ground, which of the following proportions can be used to estimate the height of the tree?

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

when you realize that you dont know just realize i just took a test and im so smart

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
