- Evaluate:

If you mean: (3x)^-1
When you have a power to a negative number (1 in this case), place the power on the numerator, with the base in the denominator.
(3x)^-1 = 1/3x
1/3x, or C) is your answer

Answer:
y = 7 sqrt(2)
Step-by-step explanation:
Since this is a triangle, we can use trig functions
sin theta = opp/ hyp
sin 45 = 7/y
y sin 45 = 7
y = 7/ sin 45
y = 7 / (1/sqrt(2) )
y = 7 sqrt(2)
