If angle a = 44° and angle b = 42° what is the length of angle c?
| 76° | |
| 94° | |
| 61° | |
| 112° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 44° - 42° = 94°

Which of the following is not true about both rectangles and squares?
the area is length x width |
|
the perimeter is the sum of the lengths of all four sides |
|
all interior angles are right angles |
|
the lengths of all sides are equal |
A rectangle is a parallelogram containing four right angles. Opposite sides (a = c, b = d) are equal and the perimeter is the sum of the lengths of all sides (a + b + c + d) or, comonly, 2 x length x width. The area of a rectangle is length x width. A square is a rectangle with four equal length sides. The perimeter of a square is 4 x length of one side (4s) and the area is the length of one side squared (s2).
The dimensions of this cube are height (h) = 5, length (l) = 9, and width (w) = 4. What is the volume?
| 32 | |
| 180 | |
| 105 | |
| 20 |
The volume of a cube is height x length x width:
v = h x l x w
v = 5 x 9 x 4
v = 180
