A circle is characterized by radius, arc, sectors and circumference
- The length of the major arc is
- The radius of the circle is 15
- The area of the shaded sector is
<h3>Length of the major arc</h3>
The given parameters are:
--- the circumference
-- the center angle
The length of the major arc is calculated using:
So, we have:
Evaluate
Hence, the length of the major arc is
<h3>The radius of the circle</h3>
The circumference is given as:
So, we have:
Divide through by 2pi
Hence, the radius of the circle is 15
<h3>The area of the shaded sector</h3>
The area of a sector is:
So, we have:
Evaluate
Hence, the area of the shaded sector is

Answers:
<h2>17. B</h2><h2>18. B</h2>
Step-by-step explanation:
17. We need to understand what an indirect proof is. In an indirect proof, you prove a statement by showing that the negation of the statement is false.
The "then" part of the conditional is the "to prove" statement.
In an indirect proof, we assume the opposite of what we want to prove, this is also called proof by contradiction.
So if we need to prove angle A is not an obtuse angle, we will assume it is and then use the proof format to show that angle A cannot be obtuse.
<h2>The answer is B: Assume angle A is an obtuse angle</h2>
18. This question is asking us to use an indirect proof again. The "then" part of the statement is "KL > JK" and is the "to prove" statement.
We need the opposite of this, which would be assuming that KL <u><</u> JK.
<h2>The answer is B: Assume that KL <u><</u> JK</h2><h2>I'm always happy to help :)</h2>
Answer: 80% of the 10 people saw the show.

Answer:
slope = - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 2 ← is in slope- intercept form
with slope m = - 3
