. Question ! . Score: 0/4 0/3 answered Oblique Triangles Question 2 an angle between Do " and iso . right angle an angle between 0" udied how to find missing sides and angles of right triangles. that is triangles containing one right angle and two acute angles. The next several activities will focus on oblique triangles. which are triangles that do not contain a right may contain one obtuse angle and two acute angles. in which case it is called an obtuse triangle. The Law of Sines one as in third angles of an oblique triangle are often labeled so that side a is across from angle A, and so Given an oblique triangle labeled as on the previous page, the law of sines says that a sin C These relationships can help when determining missing angles and side lengths in triangles. We know that the sum of the three angles in a triangle is always 180, in the for whether the triangle is acute or obtuse Deter Part At A - 17', C - 68 Example: B -[Seed an answer Suppose that in a triangle, B - 42, C - 65, and c - 12 cm. Determine side b. Round to the nearest tenth. Part B: B - 41', C - 730 Solution : 14) Calculator If we substitute the given information into sin B gin . we obtain Submit Question b 12 sin(420 ) sin(65) b = _ 12 sin(42 ) ~ 8.9 cm sin (65 ) Two observers , at points A and B are in line with glider. Round your answer to the nearest foot Find the indicated side of each triangle. Round your answers to the nearest tenth.
