6v = 54
v = 9
The answer is 32 because the inscribed angle is 16 and the intercepted arc would be twice that since you have to half it in the formula.
22)
(x^2-16)(x^2+4)=0
can you finish?
solve for x (plus and minus because two solution and degreee 4 so total 4 answers )
x=+-4 x=+-2
hope this helps.
for 10 I know a way but it might confuse you
