The Sine Law – Part I

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. ................
