This is a educated guess, but x is 80 and y is 100.
Step-by-step explanation:
My logic here is that the triangles are the same because of all the congruent lines and stuff. But from there, you know that both the right and the left side are 40 degrees. You know the total degree of a triangle is 180 so 180 - 40 - 40 is 100. So the final angle is 100. If you look at x, its on the outside, but on a line. If you can imagine a circle, its half, so its a 180 degrees total. Then its 180 = x + 100. So x is 80. And then by that same logic its y = 100.
Given that g(x)=10x^2-100x+213 in vertex form is: g(x)=10(x-5)2-37 The vertex form of an equation is given by the formula: f(x)=a(x-h)^2+k where the vertex is: (h,k) Therefore fro our expression the vertex of g(x) is (5,-37)
