Is there a pic showing ABC? it will be evil if BC is the hypotenuse itself lol
assuming dats not the case here,
tan B = CA/BC
so 0.58333 = CA/12
CA = <span>69.9996
the hypotenuse, AB = sqrt (12^2 + </span><span>69.9996^2)
= 71.02
= 71.0

Answer:
B. -5.20.
Step-by-step explanation:
We can see that Janet made more in week 4 then in week 2, so that means the answer will have to be a negative. To find the exact answer, we take away 21.74 from 16.54. This gets us -5.2, which is equivalent to -$5.20. I hope this helps!
Answer:
No Real Solutions
Step-by-step explanation:
So we have:

First, determine the domain restrictions. The expression under the radical cannot be less than 0. Therefore:

Therefore, our final answers must be greater than or equal to 3:
Now, going back to the original equation, subtract x from both sides:

Now, square both sides:

Distribute:

Subtract 4x and add 12 to both sides:

This isn't factor-able. Let's use the quadratic formula. a is 1, b is -4 and c is 12:

Substitute:

Simplify the radical:

The number under the radical is negative. In other words, there are no real solutions.
