Question

What is the length of the line TR​

Answer 1

`\Large \boxed{\sf 15}`

Explanation:

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

`\displaystyle (4)/(6) =(10)/(TR)`

`TR= 15`

Answer 2

15

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
