The diagram to the right depicts the Snoopy balloon in the Macy's Thanksgiving Day Parade. If the balloon is 63 feet off
the ground, use the given angles of elevation to determine
the length of the Snoopy balloon. Round to the nearest
whole number. (GSRT-8)
A) 53 feet
B) 48 feet
C) 101 feet
D) 149 feet

step-by-step explanation:

it's 15

true

step-by-step explanation:

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

5
