Best ResponseYou've already chosen the best response.07. To use the law of sines, which of the following statements must be true? A. All three side lengths must be known. B. At least one side length and opposite angle pair must be known. C. At least two angles must be known. D. The triangle must be a right triangle.

Best ResponseYou've already chosen the best response.08. An angle in a right triangle is identified as θ. If the tangent of θ equals one, what must be true about the triangle side lengths? A. The side opposite to theta is longer than the adjacent side. B. The side adjacent to theta is half the length of the hypotenuse. C. The sides opposite and adjacent to theta are the same length. D. The side adjacent to theta is longer than the adjacent side.
