Question

What is the length of the line TR​

Answer 1

Answer:

$\Large \boxed{\sf 15}$

Step-by-step explanation:

Both triangles are similar so the two corresponding sides are proportional.

$\displaystyle \frac{4}{6} =\frac{10}{TR}$

$TR= 15$

Answer 2

Answer:

15

Step-by-step explanation:

If the other triangle is part of the problem the triangle increased by 2.5

2.5 * 6 is 15

so 15 is the length of TR
