The Sears Tower in Chicago is 1454 feet high. Sketch and find the angle of elevation from a point 750 feet from the base to the

liq [111]

Answer: A. 62.7

Step-by-step explanation:

Using the Pythagorean Theorem, know the distance from the top of the tower to the spot on the ground 750 feet away is 1636 feet.

Now with all lengths of the triangle we can solve for the angle giving us 62.7169723304

Now we round to the tenth as instructed and get an answer of 62.7

The Maxair amusement park ride consists of a circular ring that holds 50 riders. Suppose that the center of the ride is at the o

Trava [24]

The approximation of the circumference of the ride is 138 feet to the nearest foot

<h3>How to determine the circumference?</h3>

The given parameters are:

Center (a,b) = (0,0) i.e. the origin
A circular ring, (x,y) = (16,15.1)

The radius is calculated using:

$r = \sqrt{(x - a)^2 + (y -b)^2}$

So, we have:

$r = \sqrt{(16 - 0)^2 + (15.1 -0)^2}$

Evaluate

r = √484.01

Evaluate the square root

r = 22.0

The circumference is calculated using

C = 2πr

So, we have:

C = 2π * 22.0

Evaluate

C = 138

Hence, the approximation of the circumference of the ride to the nearest foot is 138 feet
