PLEASE HELP 20 POINTS

Step2247 [10]

Answer:

x = 20

Step-by-step explanation:

If a line is parallel to a side of a triangle and it intersects the other two sides then it divides those sides proportionally.

This is the case here thus

$\frac{11}{121}$ = $\frac{10}{5x + 10}$ ( cross- multiply )

11(5x + 10) = 1210

55x + 110 = 1210 ( subtract 110 from both sides )

55x = 1100 ( divide both sides by 55 )

x = 20
