Circle O and circle P, with radii 3 and 5, respectively, are both tangent to line l at H. Enter all possible lengths of OP separated by commas.
thanks in advance to anyone who answers!
Could be they are tangent on opposite sids of the line
then OP = 3+5 = 8
if they are tangent on the SAME side of the line ( one circle is inside the other) then OP would be 5 - 3 = 2 units
