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 <em>correct answer</em> is:


B) Substitution property of equality


Explanation:


sin²x and cos²x have been added together, making

sin²x + cos²x.


Since we know that sin x = a/c, this means that sin²x = (a/c)² = a²/c².

Since we know that cos x = b/c, this means that cos²x = (b/c)² = b²/c².


These two values have been substituted for sin²x + cos²x, making

a²/c² + b²/c².


Since we substituted, this means it is the substitution property of equality.
