Answer:
Arc AC = 90°
Step-by-step explanation:
Postulate:
The measure of an arc will ALWAYS be equal to the measure of the central angle of the circle.
The angle of arc AC is marked with a square.
That square mark means it is 90°.
So the arc would also measure 90°.

second question:
January: 32 · 22 + 38 · 18 = 704 + 684 = 1388
December: 18 · 22 + 40 · 18 = 396 + 720 = 1116
1388 - 1116 = 272
Answer: $272.
1. determine the defined range
2. write all numerators above the common denominator
3. remove parenthesis
4. collect like terms
5. multiply both sides by (2x+1) x (2x-1)
6. simplify the product
7. multiply parenthesis by -4
8. cancel equal terms
9. move constant to the right
10. add the numbers
11. divide both sides by 6
ANSWER: x = 11/6
