To solve this, you need to know the formula to find the circumference of the circle. It is: C=2(pie)r.
C is what you are finding.
Pie is 3.14(you already got that).
R is the radius.
There is not enough information to solve your problem, but I hoped the equation helped!
Answer:
23°
Step-by-step explanation:
The smallest angle will be X, since it is unknown. The second is three times the first (3X) and the third is X + 65, sum the three angles and equal it to180. Solve for X and substitute in the equation

Answer:
Hi, I think it's DEGF
Step-by-step explanation:
for y=x－2,
just move y=x down 2 units.
for x=－2,
it's the easiest one, just see if there is a vertical crossing －2 on the x-axis.
for－2x+4,
you can see it as move y=－2x up 4 units, and for y=－2x, you can find it out by sub (1,-2) and (0,0) onto the graph.
for x²-4,
see it as y=x² moved down 4 units. for y=x², it's simply a parabola which is symmetrical along y-axis and crossing (0,0). And remember that since the coefficient of x² is positive, the graph is open upward.
Hope this will help u!!
