Answer:
B x=-6
x=2
Step-by-step explanation:
5x^2-x(x+4)
5x^2-x^2-4x
4x^2-4x is your answer
Multiply both sides by 2 to cancel out the 1/2 and you get 2a=bh then divide both sides by h to isolate b and you get (2a)/h=b

Answer: 29.5 degrees</h3>
==============================================
Explanation:
Add up the arc measures and divide by 2 to get the angle formed by the two chords.
angle AOB = (arc AB + arc CD)/2
angle AOB = (34 + 25)/2
angle AOB = 59/2
angle AOB = 29.5 degrees
