Which of the following statements will NOT prove that triangle ABC ~= triangle DEF?

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
