Arc Length and Radians question- please help! Will mark brainliest! Is 20pts!

The answer is shown but please give me an explanation so I can show my work!

Given:

Given that the radius of the merry - go - round is 5 feet.

The arc length of AB is 4.5 feet.

We need to determine the measure of the minor arc AB.

Measure of the minor arc AB:

The measure of the minor arc AB can be determined using the formula,

Substituting arc length = 4.5 and r = 5, we get;

Multiplying the terms, we get;

Dividing, we get;

Dividing both sides of the equation by 0.087, we get;

Rounding off to the nearest degree, we have;

Thus, the measure of the minor arc AB is 52°

52°

Step-by-step explanation:

Arc length = (theta/360) × 2pi × r

4.5 = (theta/360) × 2 × 3.14 × 5

theta/360 = 45/314

Theta = 51.59235669

probability for j is 1/4

while

a is 1/6

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
