3. Find all the sides and angles in the triangles ABC and PQR, whose descriptions follow. Draw the figure first and check your answers by using a property of triangles not already used in the calculations. (a) The triangle ABC has a right angle at C, the angle at A is 30°, and the side opposite B is 8v3 cm in length. Exact values are required for any angles or sides that you find. (b) In the triangle PQR, the angle at P measures 55°, the side PQ is 13.6 cm in length, and the side PR is 10.3 cm in length. (Give your answers correct to one decimal place.)
