WebUse the Law of Sines to get one possible angle A: sin (A)/a=sin (C)/c sin (A)/5.6=sin (31)/3.9 sin (A)=5.6sin (31)/3.9 A=arcsin (5.6sin (31)/3.9)=47.6924 Subtract 31 (C) and this angle (A) from 180 to find the third angle (B=101.3076) and use the Law of Sines again to find the third side. WebThe law of cosines states that, in a scalene triangle, the square of a side is equal with the sum of the square of each other side minus twice their product times the cosine of their angle. The law of cosines relates the length of each side of a triangle, function of the other sides and the angle between them.

WebLaw of Sines If a, b and c are the lengths of the legs of a triangle opposite to the angles A, B and C respectively; then the law of sines states: a sin A = b sin B = c sin C Equations … WebTrigonometry Ratios-Sine, Cosine, Tangent. The trigonometric ratios of a triangle are also called the trigonometric functions. Sine, cosine, and tangent are 3 important trigonometric functions and are abbreviated as sin, cos and tan. Let us see how are these ratios or functions, evaluated in case of a right-angled triangle. cinestar tv programi danas
