WebOct 6, 2024 · In Chapter 2, when we graph the trigonometric functions we will typically use radian measure. Solve the triangle. Round side lengths to the nearest 100th and angles to the nearest 10th of a degree. We can find the third side of the triangle by using the Pythagorean Theorem. a2 + 52 = 82 a2 + 25 = 64 a2 = 39 a = √39 ≈ 6.24 WebWe know angle C = 37º, and sides a = 8 and b = 11 The Law of Cosines says: c2 = a2 + b2 − 2ab cos (C) Put in the values we know: c2 = 82 + 112 − 2 × 8 × 11 × cos (37º) Do some calculations: c2 = 64 + 121 − 176 × 0.798… More calculations: c2 = 44.44... Take the square root: c = √44.44 = 6.67 to 2 decimal places Answer: c = 6.67 How to Remember
