Question

What is the value of x

Answer 1

x = 20

Explanation:

given a line parallel to a side of a triangle and intersecting the other two sides, then it divides those sides proportionally , that is

`(10)/(5x+10)` =
`(11)/(121)` =
`(1)/(11)` ( cross- multiply )

5x + 10 = 110 ( subtract 10 from both sides )

5x = 100 ( divide both sides by 5 )

x = 20
