A right angle = 90 degrees
A round angle = 360 degrees
1. 3 x 90 = 270 degrees
2. 4 x 90 = 360 degrees
3. 1 1/2 x 90 = 135 degrees
4. 2 1/3 x 90 = 210 degrees
5. 2/9 x 360 = 80 degrees
6. 3 3/8 x 360 = 1,215 degrees
Answer:
x = -5
Step-by-step explanation:
-(5x-2) = 27
Distribute the minus sign
-5x +2 = 27
Subtract 2 from each side
-5x +2-2 = 27-2
-5x = 25
Divide by -5
-5x/-5 = 25/-5
x = -5
<u>Shape #1: A square.</u>
Every side is 4 units long.
The perimeter is 16 units.
The area is <em>16 </em>square units.
<u>Shape #2: A rectangle.</u>
The length is 7.9 units.
The width is 0.1 unit.
The perimeter is 16 units.
The area is <em>0.79</em> of a square unit.
<u>Shape #3: A circle.</u>
The diameter is (16/π) units. (about 5.093 units)
The perimeter (circumference) is 16 units.
The area is (64/π) square units. (about <em>20.37</em> square units)
