Hello,
When we have a quadrilateral inscribed in a circle, the opposite angles add up to 180 degrees (supplementary).
Therefore, we can write and solve the following equation first with angles B and D.
3x + 9 + 2x - 4 = 180
5x + 5 = 180
5x =175
x = 35
Then, sub 35 in the expression for angle A and you will get:
2(35) + 3
70 + 3
73
Angle A is 73, that would make angle C equal to 107 degrees, because 180 - 73 = 107.
Good luck,

Answer:
y=-1/3x+5
Step-by-step explanation:
<u>Slope-intercept form</u>
y=mx+b
m => slope
b => y-intercept
<u>Slope</u>
m=(y2-y1)/(x2-x1)=(5-4)/(0-3)=1/(-3)=-1/3
<u>Y-intercept</u>
y=-1/3x+b
5=-1/3(0)+b
5=b
<u>Final equation</u>
y=-1/3x+5
10t - 4t + 3t = 8
13t - 4t = 8 (will do addition first)
9t = 8
So, Tanisha’s equation will be equivalent
As Tanisha’s equation is :
9t = 8
Answer: (x-y)/3 + 8
Step-by-step explanation: x -y because the it says difference between x and y and then divided by 3(the whole thing) and then added by 8, so you add 8 to the whole thing after.
