Question

directions: solve for x. 11. 12. 13. 14. 15. 16.

Explanation:

Step1: Use similar - triangles property

For the first problem (number 11), if we assume the two triangles formed by the parallel - lines are similar. The ratios of corresponding sides are equal. So, $\frac{25}{48}=\frac{30}{x}$.

Step2: Cross - multiply

Cross - multiplying gives us $25x = 48\times30$.

Step3: Solve for x

$x=\frac{48\times30}{25}=\frac{1440}{25}=57.6$.

Answer:

$x = 57.6$
