On this circle, a line segment connecting point A to point D is called:
circumference |
|
radius |
|
chord |
|
diameter |
A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).
Solve for x:
x - 5 < -1 + 2x
| x < -\(\frac{1}{5}\) | |
| x < -4 | |
| x < \(\frac{7}{9}\) | |
| x < -\(\frac{1}{9}\) |
To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the < sign and the answer on the other.
x - 5 < -1 + 2x
x < -1 + 2x + 5
x - 2x < -1 + 5
-x < 4
x < \( \frac{4}{-1} \)
x < -4

A right angle measures:
180° |
|
45° |
|
360° |
|
90° |
A right angle measures 90 degrees and is the intersection of two perpendicular lines. In diagrams, a right angle is indicated by a small box completing a square with the perpendicular lines.
If AD = 30 and BD = 20, AB = ?
| 1 | |
| 5 | |
| 10 | |
| 17 |
The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD
Solving for AB:AB = AD - BD
