I think that the best answer here would be that A = 40 degrees.
Ok got it. If you have any questions just ask in the chat below :)
First find slope
(7-5)/(3-5) = 2/-2 = -1
Slope intercept: y = mx + b
Y = -1x + b, plug in point
5 = -1(5) + b, b = 10
Equation: y = -1x + 10
Answer:
107 degrees
Step-by-step explanation:
For an inscribed quadrilateral, the opposite angles are supplementary. Thus, B+D = 180 and you can solve for x.
3x+9+2x-4 = 180
5x = 175
x = 35
Next, plug the x value into angle A.
2(35) + 3 = 73
Angle C is the supplement of this which is 180-73 = 107
