Order the following types of angle from least number of degrees to most number of degrees.
acute, obtuse, right |

An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
On this circle, line segment CD is the:
circumference |
|
chord |
|
radius |
|
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).
The dimensions of this trapezoid are a = 5, b = 2, c = 7, d = 7, and h = 4. What is the area?
| 26 | |
| 12 | |
| 18 | |
| 16\(\frac{1}{2}\) |
The area of a trapezoid is one-half the sum of the lengths of the parallel sides multiplied by the height:
a = ½(b + d)(h)
a = ½(2 + 7)(4)
a = ½(9)(4)
a = ½(36) = \( \frac{36}{2} \)
a = 18
Solve for z:
-3z + 2 > -3 + 9z
| z > -1\(\frac{3}{5}\) | |
| z > \(\frac{2}{3}\) | |
| z > \(\frac{3}{5}\) | |
| z > \(\frac{5}{12}\) |
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.
-3z + 2 > -3 + 9z
-3z > -3 + 9z - 2
-3z - 9z > -3 - 2
-12z > -5
z > \( \frac{-5}{-12} \)
z > \(\frac{5}{12}\)
