WebJul 28, 2014 · The law of sines states that. XY/sinZ = YZ/sinX = ZX/sinY. So, we need atleast two angles and one side or two sides and one angle required to find the other. Since we don't have the enough data, we can find the angle using Law of sines. But we can calculate the angle by using Sin function or cosine rule. cosZ = (x^2+y^2-z^2)/2xy. WebJun 23, 2024 · In a right triangle, the hypotenuse has endpoints XY as shown in the given graph. Since XY is hypotenuse and Z is third vertex in the triangle, therefore XZ and YZ must be perpendicular at point Z. The coordinates of X are (-4,2), so draw a vertical line x=-4 and a horizontal line y=2.
