It takes bottling machine to fill 4500 bottles in 30 minutes.
We know that
in the right triangle
sin x=opposite side angle x/hypotenuse
opposite side angle x=66 mm
hypotenuse=79 mm
so
sin x=66/79
x=arc sin (66/79)-------> x=56.66°-------> x=56.7°
the answer is
x=56.7°
Answer:
4x
Step-by-step explanation:


5x-30y=-35
Divide both the side by 5 and we get
x-6y = -7
x = 6y -7
