Cosine Law Problems A triangle has sides equal to 4 m, 11 m and 8 m. Find its angles (round answers to 1 decimal place). A ship leaves port at 1 pm traveling north at the speed of 30 miles/hour. At 3 pm, the ship adjusts its course 20 degrees eastward. How far is the ship from the port at 4pm? (round to the nearest unit). 1. A triangle has sides equal to 4 m, 11 m and 8 m. Find its angles (round answers to 1 decimal place). According to the law of cosines: (AC)^2= (AB)^2+ (BC)^2-2 (AB) (BC)\cos (\angle B) (AC)2 = (AB)2 +(B C)2 −2(AB)(B C)cos(∠B) Now we can plug the values and solve: ...
