can i get help

OpenStudy (andrewkaiser333):

OpenStudy (andrewkaiser333):

i tryied doing this but i think i messed up or did not do it right

OpenStudy (anonymous):

whats the actual problem

OpenStudy (andrewkaiser333):

use the theorems and postulates and find X

OpenStudy (andrewkaiser333):

click picture to see what it looks like on my page i am doing homework on

OpenStudy (andrewkaiser333):

can you help me understand

OpenStudy (andrewkaiser333):

i gtg i got practice

OpenStudy (ranga):

|dw:1382484306835:dw|

OpenStudy (ranga):

Angle A = Angle B Angle B = Angle C So Angle A = Angle C 3x + 10 = x^2 Solve for x

OpenStudy (andrewkaiser333):

oh i looked at it all wrong thinking it was a polynimal oops

OpenStudy (andrewkaiser333):

just got back from band practice

OpenStudy (ranga):

It is a quadratic equation. Subtract (3x + 10) from both sides and solve the quadratic equation for x.

OpenStudy (andrewkaiser333):

ok yeah i definately looked at it all wrong by mistake

OpenStudy (ranga):

What do you get for x?

OpenStudy (andrewkaiser333):

before or right now with this one you told me about to try

OpenStudy (ranga):

now.

OpenStudy (andrewkaiser333):

x^2 is x right?

OpenStudy (andrewkaiser333):

so i know i am calculating it right

OpenStudy (ranga):

what do you mean x^2 is x?

OpenStudy (andrewkaiser333):

if you x X twice you still have x right?

OpenStudy (andrewkaiser333):

x=5

OpenStudy (ranga):

Yes. And make sure what the question is. Are they asking you what x is or what the angle is? If it is x you can say x = 5. But if it is the angle, you have to put x = 5 for either of the angle and calculate the angle. Both angles should give you the same value for x = 5.

OpenStudy (andrewkaiser333):

thanks

OpenStudy (ranga):

you are welcome.
