If the base of this triangle is 1 and the height is 4, what is the area?
| 30 | |
| 36 | |
| 2 | |
| 54 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 1 x 4 = \( \frac{4}{2} \) = 2
Which of the following expressions contains exactly two terms?
monomial |
|
binomial |
|
quadratic |
|
polynomial |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
On this circle, a line segment connecting point A to point D is called:
chord |
|
radius |
|
diameter |
|
circumference |
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).
If angle a = 70° and angle b = 59° what is the length of angle d?
| 144° | |
| 157° | |
| 110° | |
| 122° |
An exterior angle of a triangle is equal to the sum of the two interior angles that are opposite:
d° = b° + c°
To find angle c, remember that the sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 70° - 59° = 51°
So, d° = 59° + 51° = 110°
A shortcut to get this answer is to remember that angles around a line add up to 180°:
a° + d° = 180°
d° = 180° - a°
d° = 180° - 70° = 110°
