      Example 1: Consider right DEF pictured at right. We know one acute angle and one side, and our goal is to determine the length of the unknown side x. Step 1: Place your finger on the 38° angle (the acute angle), and then. label the three sides: the hypotenuse. is always the longest side; the side. you are not touching is the opposite

      Note that the angle in the triangle at the bottom right is a right angle. Solution: Since we are given one side and the hypotenuse, we will first find the angle opposite the given side, so we will use the sine ratio. After we find that angle, we will use the fact that the three angles sum to 180° to find the other angle.

      The Law of Sines works just as well if the side c is given instead of the angle C. In that case, we solve for sin(C) and then use the inverse-sine function to calculate the angle C. Example 2: Find the size of angle A in the illustrated triangle: C=79(, a=36 mm, and c=50. mm. Considering significant digits, the final answer is A = 45

      No, these two triangles are not identical. They have two of the same angle measures and one side length is the same, but the sides and angles are arranged differently in each triangle. In the triangle on the left, the side marked 12 is adjacent to the . 95 ∘ angle. In the triangle on the right, the side marked 12 is adjacent to the 70 ∘ angle.
