Answer:
The measure of arc EF = 41°
Step-by-step explanation:
Given:
Arc DE = 73°

Now, we know from central angle theorem that the measure of central angle by an arc is twice that of the angle made by the same arc at the circumference. Therefore,

Now, we know that sum of all arcs on a circle is equal to 360°.
Therefore, arc DGF + arc DE + arc EF = 360°

Therefore, the measure of the arc EF is 41°.
This is a linear function.
A linear function is a straight line that has a slope, and follows the formula: <em>
y = mx + b</em>
In which:
y = y
m = slope
x = x
b = y -intercept

Cos(x°) = (√3)/2
cos⁻¹[(√3)/2] = x°, that means x° = 30°
Multiply 250 by 120 and the answer is 300,000ft2
The base fee is 4 dollars, and the thing the at changes is x or the hours so the equation is 4 + 2x equals 12. and to solve for x we have to first subtract both sides by 4, getting 2x equals 8 then we divide both sides by 2 to get x equals 4 or 4 hours
