Suppose cos ( A ) = 4 5 . cos ⁡ ( A ) = 4 5 . Use the trig identity sin 2 ( A ) + cos 2 ( A ) = 1 sin 2 ⁡ ( A ) + cos 2 ⁡ ( A ) = 1 to find sin ( A ) sin ⁡ ( A ) in quadrant I V . I V . Round to ten − - thousandth.

X+ y = k 2x + 3y = k + 1 the point of intersection of the lines has an x-coordinate of a.2k + 1 b.-2k + 1 c.2k - 1
