Answer:
a = 26°
b = 48°
c = 26°
d = 106°
Step-by-step explanation:

a = c (Alternate angles)


Corresponding angles
(a + d) + b = 180° (Interior angles)

There is no solution to this, due to X can be equal anything. Hope this helps!
Answer:
22
Step-by-step explanation:
The standard form for an equation of a circle is
, where h is the x coordinate of the center of the circle, k is the y coordinate, and r is the radius of the circle. Therefore, the radius of this circle squared is 121, meaning that the radius of the circle is 11. Since the diameter of a circle is twice the radius, the radius of this circle is 22. Hope this helps!
You should ask your parent/guardian
or teacher if needed! Merry Christmas!
15; it represents the one-time sign-up fee
The y-intercept can be found either on the graph where the line intercepts the y-axis, or b in the equation y=mx+b.
It represents the fee because it will be charged even if the number of months (x) is zero. 10 is the monthly fee because it is multiplied by x, the number of months.
