Answer:
13
Step-by-step explanation:
(180-(11v+15)+9v-8+6v-9=180
4v+148=180
4v=52
v=52/4
=13°
For this case, what we must do is find three times the perimeter of the figure.
The length of the arch is given by:
Where,
r: radius of the circle
alpha: central angle in radians
We have then:
Then, the perimeter of the figure is:

Answer: one number is 104, the first number is 26 and the third number is 126
How to:
Let’s say the “first number” is Y, the “second number” is X, and the “third number” is Z. This makes Y=4x and Z=x+100. Then put it into an equation to find the sum: X+4x+x+100=256. Take away 100 from both sides of the equation and combine the like terms (the X’s). That leaves 6x=156. Then divide both sides by 6 to get x alone which is x=26. That is the first number. To find Y just multiply X by 4 and that’s Y=104. And lastly add 100 to x which is Z=126.
