Answer:
Step-by-step explanation:
first lets add our two given angles, 90 (the little square) and 146
146 + 90 = 236
then subtract that from 360 to get our missing angle
360 - 236 = 124
so your answer is 124 degrees

Area of a circle=πr²
area of this cirlce=π*(12 ft)²=144π ft²≈452.39 ft².
answer 1= the area of this circle is 452.39 ft².
Perimeter of a circle=2πr.
Perimeter of this cirlce=2π(12 ft)=24π ft≈75.4 ft
<span>answer 2= the perimeter of this cirlce is 75.4 ft.</span>
Your answer, in your set notation, is
{-2, 7}
Answer :
- Total number of people in the room = 18
- Number of people with red hair = 2
- Number of people not with red hair = 18 - 2 = 16
- Probability of picking a person who doesn't have red hair =

Probability = 16/18
Reduce the fraction with 2
Probability = 8/9
