Answer:
- Right Angle Triangle – A Right triangle is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry (opposite, hypotenuse, adjacent).
- Obtuse Triangle – An obtuse triangle is a triangle with one obtuse angle (greater than 90°) and two acute angles.
- Acute Triangle – An acute triangle is a triangle with three acute angles (less than 90°).
12 - Right Angle Triangle
13 - Obtuse Triangle
14 - Acute Triangle
15 - Acute Triangle
16 - Right Angle Triangle
17 - Obtuse Triangle
Answer:
The coefficient is "12"
Step-by-step explanation:
Step 1: Encircle the variable along with its power whose coefficient we are finding.
Step 2: Leave that variable and consider all other numbers or variables written with it. That will be the coefficient.
First, simplify out the brackets:
-20 - 4n = -12
Then, combine like terms by moving the -20 to the other side
-4n = -12 + 20
-4n = 8
Divide by -4 on both sides to isolate the n
n = 8/-4
n = -2
48 divided by 2 = 24
3333 divided by 6 = 555.5
