PLEASE HELP. I CAN'T FIGURE THIS OUT

Answer:The answer to your question is   A = 51.37     B = 38.7°  c = 19.2 cmStep-by-step explanation:DataRight triangleC = 90°A = ?B = ?a = 15 cmb = 12 cmc = ?Process1.- Calculate the length of c.     c² = a² + b²-Substitution     c² = 15² + 12²-Simplification      c² = 225 + 144      c² = 369      c = 19.2 cm2.- Calculate the angles∠A   sin A = Opposite side / hypotenuseOpposite side = 15    hypotenuse = 19.2sinA = 15/19.2sinA = 0.781sin⁻¹A = A = 51.373.- Calculate Bsin B = 12 / 19.2sin B = 0.625sin⁻¹B = B = 38.7°
