The missing justification in the proof is <span>B) Substitution property of equality
The expression for sin</span>² x and cos² x is substituted to the other side of the equation. Since sin x = a/c, then sin² x = a²/c². Similarly, since cos x = b/c, then cos² x = b²/c². Adding to two results to the third statement.
The order that the pitcher threw is F, C, F, F, C, C, F, F, F then the next five pitches are C, C, C, C, F, F, F, F, F assuming the pitcher maintains this order
