What exactly is the question?
Quite simple, when asked for g(7) we look at 7 on the x axis (the # on the bottom) and go up to see where it is on the line.
For 7, we go between 6 and 8 and go up. It crosses the line at 4 therefore g(7) =4
Answer:
The correct answer is D. 360°
Step-by-step explanation:
The sum of all the exterior angles of a regular n-gon or a polygon is always equal to 360°.
Let us consider the image attached.
First of all let us consider the triangle.
As per the property of exterior angles: The exterior angle is equal to the sum of 2 opposite interior angles.
![\Rightarrow \angle 1=\angle B + \angle C\\\Rightarrow \angle 2=\angle A + \angle C\\\Rightarrow \angle 3=\angle A + \angle B](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cangle%201%3D%5Cangle%20B%20%2B%20%5Cangle%20C%5C%5C%5CRightarrow%20%5Cangle%202%3D%5Cangle%20A%20%2B%20%5Cangle%20C%5C%5C%5CRightarrow%20%5Cangle%203%3D%5Cangle%20A%20%2B%20%5Cangle%20B)
Where
are the interior angles of the triangle.
Adding the above equations:
![\angle 1 +\angle 2 +\angle 3 = 2 \times (\angle A +\angle B +\angle C )](https://tex.z-dn.net/?f=%5Cangle%201%20%2B%5Cangle%202%20%2B%5Cangle%203%20%3D%202%20%5Ctimes%20%28%5Cangle%20A%20%2B%5Cangle%20B%20%2B%5Cangle%20C%20%29)
The sum of interior angles of a triangle is always equal to 180°
![\angle A +\angle B +\angle C = 180^\circ](https://tex.z-dn.net/?f=%5Cangle%20A%20%2B%5Cangle%20B%20%2B%5Cangle%20C%20%3D%20180%5E%5Ccirc)
![\angle 1 +\angle 2 +\angle 3 = 2 \times 180^\circ\\\Rightarrow \angle 1 +\angle 2 +\angle 3 = 360^\circ](https://tex.z-dn.net/?f=%5Cangle%201%20%2B%5Cangle%202%20%2B%5Cangle%203%20%3D%202%20%5Ctimes%20180%5E%5Ccirc%5C%5C%5CRightarrow%20%5Cangle%201%20%2B%5Cangle%202%20%2B%5Cangle%203%20%3D%20360%5E%5Ccirc)
Hence, proved that the sum of exterior angles is
.
So, the correct answer is D. ![360^\circ](https://tex.z-dn.net/?f=360%5E%5Ccirc)
Answer:
3
Step-by-step explanation:
If his son can lift three times as much weight, you'd have to multiply the amount Mr. Johnson can by three. If he can lift 14.5 pounds, that amount multiplied by three is 43.5 pounds.
