Magazine Problem 28
In Exercises 25-34, use the Law of Sines to solve (if possible) the triangle. If two solutions exist, find both. Round your answers to two decimal places. \(A\ =\ 76^{\circ}\), \(a\ =\ 34\), \(b\ =\ 21\)
Problem 28
In Exercises 27-32, determine whether the Law of Sines or the Law of Cosines is needed to solve the triangle. Then solve the triangle. \(a = 10\), \(b = 12\), \(C = 70^{\circ}\),
Problem 28
In Exercises 15-32, represent the complex number graphically, and find the trigonometric form of the number. \(-3 - i\)
Problem 29
In Exercises 15-32, represent the complex number graphically, and find the trigonometric form of the number. \(5 + 2i\)
Problem 29
In Exercises 25-34, use the Law of Sines to solve (if possible) the triangle. If two solutions exist, find both. Round your answers to two decimal places. \(A\ =\ 58^{\circ}\), \(a\ =\ 11.4\), \(b\ =\ 12.8\)
Problem 29
