Answer:
picture: the one with the triangle in red on the base (first picture of box)
Equation: a^2 + 11^2 = c^2
Step-by-step explanation:
as we can see for the first one, the equation we see is 20^2 + 8^2 = c^2, so you look for the picture with those numbers on the triangle.
and to find the equation we look at the picture and see that in the triangle the numbers are 11 and a. And we know the equation has to be 11^2 + a^2 = c^2 And see if that equation is there
