Question

A 6-m extension ladder leans against a vertical wall with its base 2m from the wall. How high up the wall does the top of the ladder reach? Round to the nearest tenth.

Answer 1

just do Pythagorean theorem. x^2+2^2=6^2. can you solve for x?

Answer 2

Yeah the Pythagorean theorem. a^2 b^2 = c^2 like what Juicstice said.

Answer 3

*a^2 + b^2 = c^2 oops.

Answer 4

x^2+2^2=6^2
x^2+4=36
36-4=32
x^2=32
\[\sqrt{32}\]
=5.6
x=6m

Answer 5

not it would be 5.6

Answer 6

oh okay i thought i had to round it

Answer 7

yea, to the nearest tenth

Answer 8

alright, so 5.6 stays the same. ok so then what's the next step

Answer 9

you have it :).

Answer 10

oh really?! lol im stupid
i thought i had to find the perimeter or something

Answer 11

nope lolz

Answer 12

alrighty thank youuu
