The measure of a minor arc equals the measure of a(n) blank angles.

Answer:
option A is correct.
Step-by-step explanation:
Minor arcs are associated with less than half of a rotation, so minor arcs are associated with angles less than 180°
Since, A minor arc is an arc smaller than a semicircle. A central angle which is subtended by a minor arc has a measure less than 180°.
The minor arc is equal to the measure of the central angle.
We could also see the angle from the figure attached to the answer.
Hence we will obtain an acute angle.
Hence, option A is correct.

Answer:
x=5, y=2
Step-by-step explanation:
To solve this system, we need to find x and y. First, let's find x. In the first equation (6x+4y=42), subtract 4y on both sides to isolate 6x. This will result in 6x=42-4y. Divide by 6 on both sides to isolate x and get x=7-y. Now we know what x equals. Go to the second equation ad plug this into it. So instead of -3x+3y=-6, you'll have -3(7-
y)+3y=-6. Use the distributive property to get -21+2y+3y=-6. Add 2y and 3y to get -21+5y=-6. Add 21 to both sides to isolate 5y and get 5y=15. Divide by 5 on both sides to isolate y and get y=3. Now that we know that y=3, we can plug this back into the equation that was bolded above so that we can find x, so we'll have x=7-
(3) since y=3, and we'll get x=7-
, or x=7-2, or x=5.
x=5
y=2
