kvv77 [185]

Answer:

583$

Step-by-step explanation:

6% is equal to 0.06, so you multiply 550 by 0.06.  which equals 33. Then, because it asks for how much Katie played, including the tax and TV, you add 33 to 550.

Given: b = 600, B = 11°, C = 75° in triangle ABC; find C. (Round the answer to the nearest whole number.)
Slav-nsk [51]

Answer:

The answer to your question is the letter B. 3,037

Step-by-step explanation:

Data

b = 600

B = 11°

C = 75°

c = ?

Process

1.- To solve this problem, use the law of sines

               b/sin B = c/sin C

2.- Solve for c

                c = b sin C / sin B

3.- Substitution

                c = 600 sin 75 / sin 11

4.- Simplification

                c = 600 (0.966) / 0.191

                c = 579.55 / 0.191

5.- Result

                c = 3037
