Really confused as to what I need to do. I tried to solve for Y and got 69 but that didn't work. Am I supposed to use a^2 + b^2= c^2? How do I do that when there are multiply letters? I really feel like there's just something I'm not seeing. Help is really appreciated, and please explain your answer.

Respuesta :

Answer:

t = [tex]\sqrt{63} \\[/tex] or 7.94

Step-by-step explanation:

Yes, you have to use the Pythagorean theorem

A^2+B^2=C^2

So, A=9, B=t, C=12

9^2+t^2=12^2

81+t^2=144

-81        -81

t^2 = 63

t = [tex]\sqrt{63} \\[/tex]

in decimal 7.94

Hope this helps :)
