Which line has an undefined slope? a. x=18 b.2y-6x=0 c. y=-9 d. y=x

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

answer:   c ?

step-by-step explanation:

x = 12

y = 1

for the points!

all you have to do is multiply them both to see how many out comes you can put:

3 x 2 = 6

you can make 6 diferent combinations of crusts and toppings.
