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
Answer:

Step-by-step explanation:
5x4+20x3-105x2
5x2( x^2 +4x -21)

The square root of 64 is 8 and the square root of 100 is 10.... so,
square root of 64/100 = 8/10
8/10 reduces to 4/5
