Hello from MrBillDoesMath!
Answer: 2
Description. Create a line from point A perpendicular to the x axis. This line, with the radius (OA) , and x axis, form a right triangle. By Pythagoras,
x-length y-length hypotenuse squared
( 3 ^ (1/2) ) ^ 2 + 1 ^ 2 = 3 + 1 = 4
So, the square of the hypotenuse (or radius OA in this case) is 4. That means OA is the square root of 4 or 2.

Answer:
∠J = 115
∠N = 65
∠M = 50
∠K = 130
Step-by-step explanation:
Sum of all the angles = 360
2x + 15 + x + 15 +x + 3x - 20 = 360
Combine like terms
2x + x + x + 3x + 15 + 15 - 20 = 360
7x + 10 = 360
7x = 360 - 10
7x = 350
x = 350/7
x = 50
∠J = 2x + 15 = 2*50 + 15 = 100+15 = 115
∠N = x +15 = 50 +15 = 65
∠M = x = 50
∠K = 3x - 20 = 3*50 - 20 = 150 - 20 = 130
It should be 31.41 bc the equation is 2•pi•radius
