Over b
Answer: a = 122*
The three angles added together form a circle or 360*.
Set a + b + c = 360 and solve for a
a + 66 + 172 = 360
Subtract 238 from both sides to get a
a = 122*
Answer:
It is irrational
Step-by-step explanation:
7.525225222....... is non terminating non reoccurring
Therefore it is irrational
Answer:
A ceiling fan has 13-inch blades (so the radius of the circular fan is 13 inches). Suppose the linear speed of the tip of a blade is 8 feet per second
Start by adding 2 to both sides to get 3r^2 = 48. then divide both sides by 3 to get r^2 = 16. square root both sides to get r = 4.
