@Unavailabilityy

OpenStudy (three_lit_for_ya_fam):

its 32 feet tall i think bro

OpenStudy (helpmeplsoml):

thats what i thinking because 16+16 is 32

OpenStudy (three_lit_for_ya_fam):

yea and you can obviously see that the tree is half the size of the building

OpenStudy (three_lit_for_ya_fam):

and i also measured it with my screen ruler

OpenStudy (helpmeplsoml):

can you help with more?

OpenStudy (three_lit_for_ya_fam):

lol im trash but okay

OpenStudy (welshfella):

use similar triangles the triangle made by the tree and the one made by the building are similar rs sorresponding sides are in the same ratio

OpenStudy (three_lit_for_ya_fam):

Assuming the rope touches the top of the tree, then by similar triangles, the building must be 32 feet tall

OpenStudy (welshfella):

AB / DB = AC / DE AB / AD = 2/1 and DE = 16 so 2/1 = AC / 16 AC = 32 = height of the building

OpenStudy (three_lit_for_ya_fam):

here

OpenStudy (three_lit_for_ya_fam):

i made something

OpenStudy (three_lit_for_ya_fam):

OpenStudy (welshfella):

* that should be AB / DB = 2/1 (second line)

OpenStudy (three_lit_for_ya_fam):

that explains it all

OpenStudy (three_lit_for_ya_fam):

xd

OpenStudy (helpmeplsoml):

OpenStudy (welshfella):

No you cant say that AB = IK beacuse you are told nothing about the lengths of these lines.

OpenStudy (welshfella):

you know that IK = JK because AB bisects IK also you know that the angles between AB and IK are right angles
