Answer:
Option b
Step-by-step explanation:
To solve this problem use the law of the sines.
We have 2 angles of the triangle and one of the sides.

The law of the sines is:

Then:


I don't know how to solve 11 but I guess I can solve 12 so I think those are the answers:
12.
(4, 53)
(5, 85)
3^-2....
exponent rule : n^-a = 1/n^a
therefore, 3^-2 = 1/3^2 = 1/9
For 2, work backwards. 93.34 divided by 18.69 equals what? That’s your E.
3, use multiplication. 4.30 times 8.60 equals your D.
4, you just do as the problem says.
5, you do the same as number 2.
6, you do the same as 3.
For the word problem, say how someone starts off with 51.15 and has to give that something to 5 people.
