(unit 1 lesson 9 formula for the area of a triangle) select all drawings in which a corresponding height h for a given base b is correctly identified

i'm sure goog can you get that answer

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

c(x)= 6x + 3

step-by-step explanation:

i think da answer is

d.square root of 3
