Answer:
x = 12.6
Step-by-step explanation:
Sum of measure of all the arcs of a circle = 360°
m(arc CD) + m(arc CED) = 360°
Since, m(arc CED) = (20x)°
And m(arc CD) = (8x + 6)°
By substituting these measures in teh expression,
(20x)° + (8x + 6)° = 360°
(20x + 8x) + 6 = 360
28x = 360 - 6
28x = 354
x = 
x = 12.64
x = 12.6

Answer: B: 41, C: 68, D: 71.
Step-by-step explanation: A triangle's angles have to add up to 180 degrees for it to be considered a triangle. If you were to add up 71, 41, and 68, then it would equal 180 degrees. This means that out of all the other measurements, these are the three possible angle measures that can be used to make a triangle.
(I figured this out by taking 3 random sides from the list there and adding them up to see if they equal 180.)
Answer:
$1025
Step-by-step explanation:
We can use the 2-point form of the equation of a line to write a function that gives Justin's salary as a function of his sales.
We start with (sales, salary) = (400, 500) and (700, 575)
__
The 2-point form of the equation of a line is ...
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
salary = (575 -500)/(700 -400)(sales -400) +500
salary = 75/300(sales -400) +500
For sales of 2500, this will be ...
salary = (1/4)(2500 -400) +500 = (2100/4) +500 = 1025
Justin's salary after selling $2500 in merchandise is $1025.
