The mechanical advantage of the pulley is 1.
<h2>Mechanical advantage</h2>
The ratio of the force produced by a machine to the force applied to it.
<h3>The formula for mechanical advantage.</h3>
Here, is output force and input force.
<h3>Given</h3>
A pulley is given.
<h3>To find </h3>
The mechanical advantage of the pulley.
<h3>How to find a mechanical advantage?</h3>
We know by Newton's first law.
P = W
where P is applied force
and W is the weight of the object.
Then
The mechanical advantage of the pulley is 1.

Lovely let’s do the cha cha side
20:15 which reduces to 4:3 or 4/3 or 4 to 3 , hope that helped have a good day
Answer:
B) 131°
Step-by-step explanation:
-4a + 139 = 4a + 123 because they are vertical angles
-4a + 139 = 4a + 123
reduce:
8a = 16
a = 2
4(2) + 123 = 131°
