9). 3 charges, 8 µC each, are located on three vertices A, B, C of an equilateral triangle with sides 1 cm each. Another charge q is located at the mid point D of the side BC. Calculate q in micro Coulomb so that net force on the charge at A due to the charges at B, C and D is zero. 10). In a right angle triangle ABC, angle ABC is 90 Degree, AB = 2 m, and...

Consider a triangle ABC like the one below. Suppose that a = 63, b = 73, and c = 27

Consider a triangle ABC like the one below. Suppose that a = 63, b = 73, and c = 27. (The figure is not drawn to scale.) Solve the triangle. Carry your intermediate computations to at least four decimal places, and round your answers to the nearest tenth. If there is more than one solution, use the button labeled "or".
