Need help asap 30 points Often times you can use similar triangles in the real
world. Sarah is attempting to find the height of a tree
by using a mirror. By the laws of physics, she knows
that the angle of incidence is congruent to the angle of
reflection (these are marked in red on the diagram).
Explain why the two triangles are similar and if she
knows her height and the distance from the mirror to her
feet and also the distance from the mirror to the tree
how could she calculate the height of the tree?
