find the surface area of a trapezoid with a width of 6.84, height of 15, and the side lengths 10, 8, 7, 13

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
