Answer:
d. 32.9
Step-by-step explanation:
To find c, we'll use the Law of Sines that says:

And we'll isolate a to get:

We first need to find A, which is easy. The sum of the interior angles of a triangle is 180 degrees... and we already have 2 of them, so:
A = 180 - 90 - 47.3 = 42.7
(converted 47°18' to 47.3)
Then we will plug-in the information we already have

So, let's round it to 32.9 to match the answer number D.
Answer:
x = 7.33
Step-by-step explanation:
3x - 15 = 7
3x = 7 + 15
3x = 22
x = 7.33
Your answer would be the last option, c = √(E/m).
We can see this when we rearrange the equation, as:
E = mc²
÷ m
E/m = c²
√
√(E/m) = c
So you got all the steps in rearranging correct :)
I hope this helps!

0.10(5000) = 500
0.15(10,000) = 1500
total commission on 15,000 = (150 + 500) = 2,000
