Answer: congruent central angles
Step-by-step explanation:
A central angle is an angle formed by two radii with the vertex at the center of the circle. In the diagram at the right, ∠AOB is a central angle with an intercepted minor arc from A to B. In a circle, or congruent circles, congruent central angles have congruent arcs.
Well,
we know that we need to accumulate points from x and y to reach 20 points.
since x provide 3 and y provide 4 points, the formula would be :
3x + 4y = 20
or it can be written as :
y = (3x/4)+5
hope this helps
Answer: 4 2/7
Step-by-step explanation:
There are 2 ways to do this I dont like a negatuve so add 20 over to 10 now we got -3x + 30=4x add 3 over to 4x we now have 30=7x we are left with 30/7. Or u could make it 4 2/7
10= 30 degrees 30+90= 120
11= 60 degrees 180-120= 60
12= 60 degrees 180-120 = 60
13= 120 degrees 180-60= 120
Makes no sense.
p.s i am a fourth grader
