2(5.9) is 11.8
Hopefully i is right I did this in my head.
Answer:
90
Step-by-step explanation:
In the quadrilateral formed by two tangents and the associated radii, the central angle and the external angle are supplementary. Here, that means that x° is supplementary to itself, so must be 90°.
x = 90
y=2x so replacr the -y with -2x so 2x+6 is 8x. :)
