WebThis online calculator determines the lengths of triangle sides given one side and two angles using the law of sines. The law of sines, also known as the sine rule, states that the ratio of the length of a side of a triangle to the sine of the opposite angle is constant for all three sides and angles. The calculator takes as input the length of ... WebCollectively, these relationships are called the Law of Sines. sinα a = sinβ b = sinλ c s i n α a = s i n β b = s i n λ c. Note the standard way of labeling triangles: angle α α (alpha) is opposite side a; a; angle β β (beta) is opposite side b; b; and angle γ γ (gamma) is opposite side c. c. See (Figure). WebThis means we are given two sides and the included angle. For this type of triangle, we must use The Law of Cosines first to calculate the third side of the triangle; then we can use The Law of Sines to find one of the other two angles, and finally use Angles of a Triangle to find the last angle.
