help!! If they make the length of the short leg of the triangle in the figure 3 in. long how long will they make the long leg?

Answer:
I may not be right but I believe it would be 147ft
Step-by-step explanation:
if you make 90 into a 3 then you will have 87 so I would think you just add 87 to 60.
AGAIN I might not be right
