Help ASAP PLEAS Use the diagram to derive the law of cosines. Fill in the missing statements in the derivation.

1) a2 = h2 + x22) h2 =
3) c2 = h2 + (b − x)2
4) c2 = h2 +
5) c2 = a2 − x2 + b2 − 2bx + x26) c2 = a2 + b2
7) x = acosC
8) c2 = a2 + b22abcosC

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0
