Often times you can use similar triangles in the real world. Sarah is attempting to find the eight 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. Explain why the two triangles are similar 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?

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d

the correct answers are 1, 2, 4, and 5! i just got it right!
