Step-by-step explanation:
Isolate z by itself:

To simplify variables with powers, subtract the smaller power from the bigger power:


The exponent will be
-3.
The variables are: x, y
The constant is: 4
The coefficients are: 5, 3
The exponent is: y^2
Answer:
Step-by-step explanation:
you have to use trigonometric functions
cos 30 = adj. /hyp.
cos 30 = 12 / y
y = 12/cos 30 ≅13.86
tan 30 = opp./adj
tan30 = x / 12
x = 12 tan30 ≅6.93
