Answer: B
Step-by-step explanation:
By the Exterior Angle Theorem, we know that the exterior angle is equal to the sum of the two opposite interior angles.
(2x+8)+(3x+5)=123 [combine like terms]
5x+13=123 [subtract both sides by 13]
5x=110 [divide both sides by 5]
x=22
Now, we know that the answer is B.
Answer:
Well 4 times 4 is 16 thats because you are multiplying its self once so 4 times 4. while 4^4 is 4 to the fourth power meaning you are multiplying the 4 four times. So 4^4 is 256.
Step-by-step explanation:
A=pR^2-2pr^2, since R=15 and r=7.5
A=225p-112.5p
A=112.5p
A≈353.25 ft^2

Therefore,
![\cos \theta=-3](https://tex.z-dn.net/?f=%5Ccos%20%5Ctheta%3D-3)
Step-by-step explanation:
Unit Circle:
In mathematics, a unit circle is a circle with a unit radius. Frequently, especially in trigonometry, the unit circle is the circle of radius one centered at the origin (0, 0) in coordinate System.
So the coordinate of point P on the circle is given as,
![P(x,y)=(r\cos \theta,r\sin \theta)](https://tex.z-dn.net/?f=P%28x%2Cy%29%3D%28r%5Ccos%20%5Ctheta%2Cr%5Csin%20%5Ctheta%29)
Here,
Given:
P(-3,2)
So if Radius is one unit i.e r = 1 then on Comparing we get
![P(-3,2)=(\cos \theta,\sin \theta)](https://tex.z-dn.net/?f=P%28-3%2C2%29%3D%28%5Ccos%20%5Ctheta%2C%5Csin%20%5Ctheta%29)
∴![\cos \theta=-3](https://tex.z-dn.net/?f=%5Ccos%20%5Ctheta%3D-3)
Therefore,
![\cos \theta=-3](https://tex.z-dn.net/?f=%5Ccos%20%5Ctheta%3D-3)
