The triangles are congruent. Find the measure of x.

Match up the sides for each triangle using the little marks through the sides

1 to 1, 2 to 2 and 3 to 3

When you do this you see that x corresponds to c on the first triangle.

The 3 angles in a triangle = 180.

Find c by subtracting A and B from 180

C = 180- 29-63 = 88

Now x = c so x = 88

The answer is C. 88

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

900 degrees
