Find the area of each triangle with angles A, B, C and opposite sides a, b, c respectively. Round answers to two decimal places. (a) B = 70 degrees, C = 10 degrees, b = 5 (b) a = 2, b = 3, C = 95 degrees (c) a = 6, b = 5, c = 8

Step 1
We can find side c using the law of sines: c/sin(C) = b/sin(B) c/sin(10) = 5/sin(70) c = 5*sin(10)/sin(70) ≈ 0.87 Now we can find angle A using the fact that the angles of a triangle add up to 180 degrees: A = 180 - B - C = 100 degrees Show more…
