Answer:
Central angle = θ = 2.5 radians
Step-by-step explanation:
The radian measure of central angle is given by
![\theta = \frac{s}{r}](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20%5Cfrac%7Bs%7D%7Br%7D)
Where s is the arc length, r is the radius of circle and θ is angle in radians
We are given an arc length of 5 units
![s = 5](https://tex.z-dn.net/?f=s%20%3D%205)
We are given radius of 2 units
![r = 2](https://tex.z-dn.net/?f=r%20%3D%202)
Therefore, the central angle in radians is
![\theta = \frac{5}{2}\\\\\theta = 2.5 \: rad](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20%5Cfrac%7B5%7D%7B2%7D%5C%5C%5C%5C%5Ctheta%20%3D%202.5%20%5C%3A%20rad)
Bonus:
Radian is a unit which we use to measure angles.
1 Radian is the angle that results in an arc having a length equal to the radius.
Degree is another unit that we use to measure angles.
There are 360° in a circle.
There are 2π radians in a circle.
Answer: a=−3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
a−2+3=−2
a+−2+3=−2
(a)+(−2+3)=−2(Combine Like Terms)
a+1=−2
a+1=−2
Step 2: Subtract 1 from both sides.
a+1−1=−2−1
a=−3
