Question

I NEED SOME HELP CHECKING AND SOLVING


Given the diagram in the comments, solve for x,y,z and the perimeter of ABCD.

So far, I've got:
x+5=17 and then when I solve that it = 12

Then by theorem 8.4, angle D=angle B so y=120degrees

Answer 1

x+5=17
x=12

angle y =120 degree too so 360-2*120=360-240=120 so than angle z=120/2 =60 degree

Answer 2

do you understand it ?

Answer 3

Yeah, I think I got it

Answer 4

so the perimeter =?

Answer 5

That I'm not sure of

Answer 6

P=2*12+2*17

ok ?

Answer 7

Got it. Okay

Answer 8

good luck

bye

Answer 9

Thanks! Bye
