Answer:

Total distance covered by the maintenance worker = 9189.16 feet

Step-by-step explanation:

An amusement park has a diameter = 975 feet

Radius of the park = $\frac{\text{Diameter}}{2}$

r = $\frac{975}{2}$

r = 487.5 feet

Since a maintenance worker walks around the park three times, that means he covers the circumference of the circle thrice.

Circumference = 2πr

C = 2π(487.5)

C = 975π feet

He covers this distance thrice,

So total distance covered by him = 3 × (975π)

= 2925π

= 9189.16 feet

Therefore, he walks 9189.16 feet per day.

Because the triangle is equilateral we know that z=60, therefore:

$60=\frac{1}{3}x-7$
$67=\frac{x}{3}$
$67 \times 3 = x$
$x=201$
