I dont know how to find a .

mina [271]

To find a,construct a line that parallel to AB and DE cutting c, which you could refer to the photo((sorry for my terrible diagram ^^;;

from the photo,we can see that
a= <BCG + <GCE

<BCG=44° (alt.<, AB//FG)
<GCE=20° (alt<, FG//DE)

thus,a= 44°+20° =64°

hope it helps!

If y varies directly as x and y=12 when x=c what is y in terms of c when x=8

tatiyna

"y varies directly as x" means y = kx

you do not know what k is yet, other than that it is some constant number.

Now plug in the given values, y=12 when x=4, in the equation

12 = 4k

=> k = 3

Now rewrite the equation with the k value you just found

y = 3k

Substitute 18 in place of x

y = 3(18)

y = 54
