Determine whether the Law of Cosines or the Law of Sines is needed to solve the triangle a = 11, b = 13, c = 7

Sveta_85 [38]

Answer:

Step-by-step explanation:

Use the Law of Cosines:

c^2 = a^2 + b^2 - 2ab*cos C becomes

7^2 = 11^2 + 13^2 - 2(11)(13)cos C.

Once you have cos C, and then side c, you can use the Law of Sines to find the other two interior angles.

(i) The given AP is 1, 5, 9, 13, 17,...

(i) The given AP is 1, 5, 9, 13, 17,... First term, a = 1 and common difference, d = (5 - 1) = 4

(i) The given AP is 1, 5, 9, 13, 17,... First term, a = 1 and common difference, d = (5 - 1) = 4 T20 = a + (20 - 1)d = a + 19d

(i) The given AP is 1, 5, 9, 13, 17,... First term, a = 1 and common difference, d = (5 - 1) = 4 T20 = a + (20 - 1)d = a + 19d = 1 + 19 ⨯ 4 = 77 

(i) The given AP is 1, 5, 9, 13, 17,... First term, a = 1 and common difference, d = (5 - 1) = 4 T20 = a + (20 - 1)d = a + 19d = 1 + 19 ⨯ 4 = 77 ∴ 20th term = 77
