Answer:
I believe it's 4
Step-by-step explanation:
Answer:
320°
Step-by-step explanation:
<u>Part 1</u>
The arc length is given by ...
s = rθ . . . . . r is the radius, θ is the central angle in radians
We want to find θ, so we can fill in the given values and divide by the coefficient of θ.
8π = 4.5θ
θ = 8π/4.5 = 16π/9 . . . radians
Since π radians = 180°, the degree measure of the angle is ...
θ = (16/9)180° = 320°
The measure of the angle subtended by the arc is 320°.

<u>Part 2</u>
We might be able to help with the second part of the question, but you need to edit to put in the numbers and answer choices.
Answer:
NO.
Step-by-step explanation:
The common difference is -4 and you can continue to add -4 for ever!!
No. A rational plus an irrational is always an irrational.
The equations state -5(3s-9)=23. So 1st you wanna multiply 3s and -9 by -5. Which would get you -15s+45=23.
Than you subtract 23 from 45 which would equal -22 and than divide 15 from that
So the equation would equal 1.47
