Answer:
B. 61
Step-by-step explanation:
The sum of arcs around a circle is 360°. This means ...
110° +128° +c° = 360°
c° = 122° . . . . . . . . . . . . . subtract 238°
__
An inscribed angle in a circle has half the measure of the arc it subtends.
a° = 1/2c° = 1/2(122°) = 61°
__
The other angles in the diagram are ...
b° = 1/2(110°) = 55°
d° = 1/2(128°) = 64°
A property of a parallelogram is that their diagonals bisect eachother. Since in part a the diagonals bisect eachother, we know for sure that it's a parallelogram.
We also know that you can make two congruent triangles with a parallelogram. Note that if you draw a line from one accute angle to the other, we create two equal triangles by SAS congruency, so since the figure is comprised of two congruent triangles, it is a parallelogram.
The right side of the equation is 6-6 which equals 0.
So the equation could be written as 3x-5y = 0
Since the right side of the equation is zero both the x and y intercepts are (0,0)
Solution
We will use sum of angles on a straight line = 180 degrees
