Imagine two lines intersect. How can the properties of linear pairs and vertical angles help to determine the angle measures cre
Art [367]
<span>Vertical angles are opposite angles that share only a vertex.
When two lines intersect, we have two sets of vertical angles.

Linear pairs are two angles that form a straight line; when two lines intersect, we have two linear pairs. 

If we know one of the angles formed when two lines intersect, we know that the angle opposite it, the vertical angle, has the same measure.
We also know that the angle beside it, that forms a linear pair, will be supplementary with it (add to 180); this means we can find its measure by subtracting from 180.
The remaining missing angle will be the same as this supplementary angle, since they are vertical angles</span>

if your bicycle tire has a diameter of 9 inches. how many rotations does each tire make if you travel 300 feet?
Vesnalui [34]
Step One
Calculate the number of feet traveled in 1 rotation.

Formula
C = π*d
P = 3.14
d = 9 inches = 9/12 feet = 3/4 of a foot.

C = 3.14 * 3/4 = 2.355 So that means that every time the tire turns around 1 complete turn, the distance traveled on the ground is 2.355 feet.
 
Step Two
Figure out the number of revolutions.
1 revolution = 2.355 feet
x revolutions = 300 feet.

1/x = 2.355/ 300  Cross multiply
2.355 feet * x = 1 rev * 300 feet
2.355 x = 300 rev Divide by 2.355
x = 300 / 2.355 
x = 127.39 revolutions. <<<< Answer

If you solve the equation for ax+by/c=d for x, what would you get?
Xelga [282]

<u>Answer:</u>

x=d/a - by/ac

<u>Steps:</u>

ax+by/c=d

(cax+by)/c=d

cax+by=cd

cax=cd-by

x=(cd-by)/ca

x=cd/ca - by/ca

x=d/a - by/ac
