I need some help on the questions.

(e) Explain how to solve the SAS triangle with c = 10, A = 36, b = 5. Is there only one way to solve this triangle, or may you solve for the elements in another order, or using different tools? (f) Give three examples of SSA triangles: one which has no solution, one which has one solution, and one which has two solutions. Explain why you know the number of solutions in each of your examples. (g) Explain how to nd the value of S = 1 + 2 + 3 + + (m 1) + m. (h) How many 4-letter words can be spelled with 'a', 'b', 'c', 'd'? How many 4-letter words can be spelled using 'x', 'x', 'x', 'y'? Explain the relationship between your two answers
