PLEASE HELP, WILL FAN AND MEDAL. :)
Find the length of side x.(Look in the next comment for the picture)
a. x = sqrt325
b. x = 15
c. x = sqrt253
d. x = 11

Pythagorean Theorem is needed to do this problem.
Directrix (directrix):
Do you know the theorem? If not, then we need to post it. @tvinsant
OpenStudy (tvinsant):
Yes. I tried but I came up with a different answer :? so I'm kinda stuck.
the formula is a^2+b^2+c^2=180
Directrix (directrix):
You have the sum of the angles of a triangle mixed up with the P Theorem

a^2+b^2 = c^2 where a and b are legs and c is the hypotenuse.
OpenStudy (tvinsant):
OHHHHHH
OpenStudy (tvinsant):
okay... sorry lol
OpenStudy (tvinsant):
so the answer is A.
Directrix (directrix):
Legs are 6 and x.

so the answer is A. I don't know.
That is why we are writing the equation - so that there is no need to guess.
OpenStudy (tvinsant):
because when you square the two and sum it up, the answer is 325. Then you'd have to square it so it'd be x=sqrt325
Directrix (directrix):
I did not get that.
OpenStudy (tvinsant):
lol ummm
OpenStudy (tvinsant):
but is the answer A?

x^2 + 6 ^2 = 17^2

>>but is the answer A? I do not know.
OpenStudy (tvinsant):
ohhh nvm is C.
OpenStudy (tvinsant):
its*
Directrix (directrix):
If you don't want to solve this x^2 + 6 ^2 = 17^2 , I'll move along.

x^2+36=289
x^2=289-36
x^2=253
sqrtx=sqrt253
Directrix (directrix):
The MaPaw site has a glitch.
sqrtx=sqrt253 should be x = sqrt253
OpenStudy (tvinsant):
oh okay
Directrix (directrix):
Now, at long last, I agree with you that C is the correct option.
OpenStudy (tvinsant):
Thank you :) Have a nice day!
