If x is the number of sides of the regular polygon, then the sum of the interior angles is (x - 2) * 180 = 56 * 90. Solving for x gives 30 for the number of sides of the regular polygon.
To get the central angles measure, divide 360 by 30 to get 12 degrees for the measure of one of the 30 central angles.
Answer: 12 degrees
6. $1.25(0.20) = 0.25
7. Coordinate 3
8. x/8 <span>≥</span> = 6
Step-by-step explanation:
We should express this word problem in an equation form:
square root of the quantity x plus 4 minus 3 equals 1 for the variable
√x + 4 - 3 = 1
The equation is:
√x + 4 -3 = 1
√x + 1 = 1
Now add (-1) to both sides;
√x + 1 + (-1) = 1 + (-1)
√x = 0
Square both sides
(√x)² = 0²
x = 0
1540 ÷ 55 = 28
the payments would be made for 28 months, or 2 years and 4 months
