Order the following types of angle from least number of degrees to most number of degrees.
acute, right, obtuse |
|
right, obtuse, acute |
|
right, acute, obtuse |
|
acute, obtuse, right |
An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
Which of the following is not a part of PEMDAS, the acronym for math order of operations?
division |
|
pairs |
|
addition |
|
exponents |
When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
If angle a = 59° and angle b = 34° what is the length of angle c?
| 121° | |
| 77° | |
| 91° | |
| 87° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 59° - 34° = 87°
Simplify (y - 1)(y + 8)
| y2 - 9y + 8 | |
| y2 - 7y - 8 | |
| y2 + 9y + 8 | |
| y2 + 7y - 8 |
To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses:
(y - 1)(y + 8)
(y x y) + (y x 8) + (-1 x y) + (-1 x 8)
y2 + 8y - y - 8
y2 + 7y - 8
