K=am+3mx
K=m(a+3x)
m=K/(a+3x)
Answer: m=K/(a+3x)
Answer: 46 degrees
Step-by-step explanation: First you need to find the value of the vertical angle which is 180-(85+53) which is 42 degrees. Since vertical angles are congruent, you can say that 180-(42+92) is equal to x. When you solve it, you get x=46 which is your answer
Answer: 1/6
-1/2 also equals -3/6
2/3 also equals 4/6
Using the number line, start at -1/2. Then, since the distance from one dash to the next on the line equals 1/6, you will move 4 spaces to the right. That should give you 1/6.
Answer:
Step-by-step explanation:
Remark
If you take one radius whose length is r and start it at (0,0) on one end and (r,0) at the other, and sweep it around so the (r,0) hits every point on the circumference of the circle, the radius will go through 360°.
You have only gone through 120°. That's no problem. All you have to do now is add a fraction that adjusts for the 120°.
Formula
Arc length = fraction * 2*pi * r
2*pi * r is the circumference
Arc Length = 2* (120/360) * pi * r
Givens
r = 13
pi = 3.14
Solution
Arc Length = (120/360) * 2 * pi * 13
Arc Length = 27.21
Answer
Arc Length = 27.21
