HEL ASAPPP PLEASE Sally built a small ramp for her bicycle. The ramp is 10 meters long and creates a
15-degree angle with the ground. How tall is the ramp at the highest point?

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-   36

taxicab circle radius 9 has 4(9) = 36 points

answer: i ! the answer is   9000 seconds, also d

hope i
