Question

Help me please it’s in the picture

Answer 1

Here is your answer

Since the line is parallel to one side of triangle, so by

Thales' theorem other two sides are divided in the same ratio.

So,


`\huge\frac {5}{40}=(3)/(2x + 10)`


`\huge => 5 (2x+10)= 3×40`


`\huge => 10x + 50= 120`


`\huge => 10x= 120-50=70`


`\huge => x=7`
