Question

Help me please :)

Answer 1

hi. what may the question be?

Answer 2

Find the missing side length.
a. 12 in
b. 15 in
c. 17 in
d. 21 in

Answer 3

they ever gave u a perimeter or anything?

Answer 4

from this point it can be anything..

Answer 5

Nope. thats all the question was. thats why i dont understand.

Answer 6

Use the Pythagorean equation

Answer 7

It's a right triangle, therefore we can use that equation to find the length of the hypotenuse.

The equation is as so:

\[c^2 = a^2 + b^2\]can you solve for "c" from here?

Answer 8

I got 18+144

Answer 9

9^2 = 81 not 18

Answer 10

Oh yeah. Oops.

Answer 11

so you found out that \[c^2 = 81+144\]how would you find "c"?

Answer 12

225

Answer 13

okay that still leaves \[c^2= 225\]we need to find the singular value of "c" not the c^2, what would you do?

Answer 14

divide by 2?

Answer 15

No. When you see a letter or number that has an exponent of "2" we say that it is "Squared" right?

so c^2 or \[c^2\] we say it's "c squared", or in expansion it looks like this \[c \times c\] how do we "unsquare" it

Answer 16

Raise it to a half power? i dont really know.

Answer 17

We square root it. It looks as so
\[\sqrt{c ^{2}}= \sqrt{225}\]You seen that before right? Now, what is your answer for singular "c"
