Have a awesome day.
It is given in the question that, PA is a radius and AB is the tangent segment .
And in a circle, radius and tangent are always perpendicular, it means they form 90 degree with each other . Or angle PAB is a right angle .
And we cant say anything about the length s of PA and AB, neither of PA and PB.
So out of the four options, correct option is the third option .
700=(4000)(0.65)x
4000 x 0.65
700=(2600)x
700=2600x
0.27=x
