Question

What is the value of x?
Enter your answer in the box.

Answer 1

Answer:

27

Step-by-step explanation:

Triangle proportionality theorem: when you draw a line parallel to one side of a triangle, it'll intersect the other two sides of the triangle and divide them proportionally

$\frac{26}{39}=\frac{18}{x}$

Cross multiply and you get 702=26x

x=27

Answer 2

Answer:

x=27

Step-by-step explanation:

-We can use the triangle proportionality theorem: if line parallel to a side of a triangle intersects the other two sides, then it divides those sides proportionally.

-we write the proportion and solve for x

$\frac{39}{26} =\frac{x}{18}$

$x= \frac{39*18}{26}$

x= 27
