Answer:
60° = π/3 radians
Step-by-step explanation:
The 10 cm length of the arc is 1/6 of the 60 cm length of the circumference of the circle. That means the angle measure of the arc is 1/6 of the total angle measure of a circle.
arc = 360°/6 = 60°
arc = (2π radians)/6 = π/3 radians

Answer:
∠1 = 64°
∠2 = 116°
Step-by-step explanation:
Let x = supplement and x + 52 = the one angle. Set up this equation:
(x) + (x + 52) = 180
2x + 52 = 180
Subtract 52 from both sides.
2x = 128
Divide both sides by 2, and you get x = 64.
Keep in mind this equals the supplement. To find the measure of the other angle, add 52 and you get 116

Is square root 14 irrational
[tex]\Large\boxed{\tt Answer: \sqrt{14} ~is~an~irrational~number.}[/tex]
[tex]\large{\tt Step-by-step~explanation:}[/tex]
If a square root isn't a perfect square, then it is an irrational number, which means that it cannot be represented as the ratio of two integers. If we input √14 into a calculator, we can see that it would equal to a repeating decimal. √14 is an irrational number.

What is the mean, median and mode for...45,50,55,55,55,60,60,60,65,65,70?
Answer:
Mean = 58.18
Median = 60
Modes = 55 and 60
Step-by-step explanation:
To find the mean/average, add up all the numbers and divide the sum by the # of numbers there are (ex. there are 11 numbers so divide the sum by 11).
The median is the middle number of a set. In this case, the middle number is easy to see because the # of numbers is odd, but if it was even, just find the average of the two middle numbers.
The mode is/are the most frequent number(s) in the set. In this set, the numbers that appear the most are 55 and 60.

(a) Prove that cos 3A = 4cos³ A - 3 cos A
Answer:
Step-by-step explanation:
cos 3A = cos (2A+A)
= cos 2A cos A - sin 2A sin A
= (2cos[tex]A^{2}[/tex] -1) cos A - (2sinAcosA) sinA
=2cos[tex]A^{3}[/tex]-cosA - 2sin[tex]A^{2}[/tex]cosA
=2cos[tex]A^{3}[/tex]-cosA -2(1 -cos[tex]A^{2}[/tex])cosA
=2cos[tex]A^{3}[/tex] - cosA - 2 cosA+ 2cos
⇒ ∴4cos[tex]A^{3}[/tex] -3 cosA
