G(x)=-x+0. Any equation reflected across the x axis will have the opposite x value as the original function. Hope this helps!

Step-by-step explanation:
the triangle is an isosceles triangle hence the base angles are equal
sum of angles in a triangle is 180°, therefore, the top angle =180-(62+62)
the top angle =56°
h°= the top angle because alternate angles are equal
hence, h=56°
