pythagoras theorem is given as:
as per the statement:
fh is tangent to circle g at point f.
as we know that at the point of tangency tangent is perpendicular to radius.
in triangle gfh.
hypotenuse side = gh = 25 + r units
adjacent side = fg = r units
opposite side = fh = 35 units
using pythagoras theorem, we have;
using identity rule:
⇒
subtract from both sides we have;
subtract 625 from both sides we have;
divide both sides by 50 we have;
r = 12 units
therefore, the length of the radius, r is, 12 units
