The dimensions of this trapezoid are a = 5, b = 5, c = 6, d = 2, and h = 4. What is the area?
| 7\(\frac{1}{2}\) | |
| 9 | |
| 14 | |
| 22 |
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(5 + 2)(4)
a = ½(7)(4)
a = ½(28) = \( \frac{28}{2} \)
a = 14
The dimensions of this cube are height (h) = 8, length (l) = 3, and width (w) = 7. What is the volume?
| 108 | |
| 64 | |
| 168 | |
| 144 |
The volume of a cube is height x length x width:
v = h x l x w
v = 8 x 3 x 7
v = 168
When two lines intersect, adjacent angles are __________ (they add up to 180°) and angles across from either other are __________ (they're equal).
acute, obtuse |
|
supplementary, vertical |
|
vertical, supplementary |
|
obtuse, acute |
Angles around a line add up to 180°. Angles around a point add up to 360°. When two lines intersect, adjacent angles are supplementary (they add up to 180°) and angles across from either other are vertical (they're equal).
If a = c = 5, b = d = 3, and the blue angle = 62°, what is the area of this parallelogram?
| 56 | |
| 18 | |
| 15 | |
| 21 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 5 x 3
a = 15
