Question

I need help. Anyone?

Answer 1

Here we have given radius AO = 30 & we know that OC is also radius
So AO=OC=30 , So we know OC= 30
now we can find BO=BC+OC=48+30=78.
We know that OA is perpendicular to AB sousing pythagoras
(BO)^2=(AB)^2+(AO)^2 just plug the values & solve for AB

Hope this will help u :)

Answer 2

ummm

Answer 3

Answer 4
