The Sine Law – Part I. In ΔABC, find the value of side c to one decimal place. Note: ΔABC in an oblique triangle! (a triangle that has no right angles) We need a 90˚ angle to use the primary. trig ratios (sin, cos, tan). To solve this problem, we can construct the altitude from B to D and create two 90˚ triangles.

sin B = (opposite side to B)/(hypotenuse) = b/c. cos B = (adjacent side to B)/(hypotenuse) = a/c. tan B = (opposite side to B)/(adjacent side to B) = b/a. Pythagorean Theorem: In a right triangle a2 + b2 = c2 (c = All Triangles. Law of Cosines: a2 = b2 +c2 – 2bc cosA. b2 = a2 +c2 – 2ac cosB. c2 = a2 +b2 – 2ab cosC. Law of sines: sinA ...
