Suppose that ∠P and ∠Q are acute angles. If sin∠P=cos∠Q , which statement must be true? A. m∠P+m∠Q=90° B. m∠P+m∠Q=180° C. m∠P=−m∠Q D. m∠P=m∠Q

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
