Answer:
Q = 69.5 degrees
Step-by-step explanation:
3x + 14 + 3x - 27 = 180
6x - 13 = 180
6x = 193
x = 32.1667
Q = 3(32.1667) - 27
Q = 69.5

Four angles must add up to 360.
∠A+∠B+∠C+∠D=360
(5/2x+30)+(7/2x+40)+(9/2x+10)+(5/2x+20)=360
26/2x + 100 = 360
13x = 260
x = 20.
To solve for ∠C, plug x back in:
∠C = 9/2x+10 = 9/2*20+10 = 100

Answer: (4, -1)</h3>
Reason:
When rotating a point 180 degrees around the origin, you use the rule

We flip the sign of each coordinate from positive to negative or vice versa.
The point X is at the location (-4, 1). Rotating this 180 degrees will get us to X'(4, -1)
