+91 Since the line that cuts through the triangle is parallel to the base, we know that 3 is proportional to x - 3 in the same way 5 is proportional to 2x-10.
Mathematically, we can represent this as:
\({\frac {5} {2x-10}}={\frac {3} {x-3}}\)
Which can then be solved to get:
\(5(x-3)=3(2x-10)\)
\(5x-15=6x-30\)
\(x = 15\)
Thus, x = 15.
Solved! :)
