Park rangers add another section to the trail, represented by the expression ++. Write an expression for the new total length of the trail. Then write a simplified equivalent expression.

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

english maybe i can ..

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q

you didn't give an question you just gave us a statement
