If angle a = 63° and angle b = 49° what is the length of angle c?
| 97° | |
| 71° | |
| 68° | |
| 109° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 63° - 49° = 68°
If a = c = 3, b = d = 1, and the blue angle = 65°, what is the area of this parallelogram?

| 3 | |
| 1 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 3 x 1
a = 3
If side x = 14cm, side y = 15cm, and side z = 11cm what is the perimeter of this triangle?
| 24cm | |
| 32cm | |
| 40cm | |
| 31cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 14cm + 15cm + 11cm = 40cm
The dimensions of this cube are height (h) = 4, length (l) = 5, and width (w) = 2. What is the volume?
| 32 | |
| 40 | |
| 128 | |
| 144 |
The volume of a cube is height x length x width:
v = h x l x w
v = 4 x 5 x 2
v = 40
A coordinate grid is composed of which of the following?
x-axis |
|
y-axis |
|
origin |
|
all of these |
The coordinate grid is composed of a horizontal x-axis and a vertical y-axis. The center of the grid, where the x-axis and y-axis meet, is called the origin.
