Question

Solve for x.
A) 10
B) 11
C) 9
D) 12

Answer 1

Answer: A) 10

Explanation:

Since the lines that cross the triangle and parallel, they will be proportional. This means we can create a proportion to help us solve.

`\displaystyle (15)/(25)= (6)/(x)`

Now, we will cross-multiply.

15 * x = 25 * 6

15x = 150

Lastly, we will divide both sides of the equation by 15.

x = 10
