Answer:

12.9

Step-by-step explanation:

So, we're looking for the side of a triangle.

We are going to use a trig function, tan(x), which is equal to the opposite side of x (the angle) over the adjacent side

In this case, tan (35) = 9/x

we then move the x to the other side by multiplying both sides by x

x * tan(35) = 9

then we divide both sides by tan(35)

x = 9/tan(35)

this answer comes out to (rounded to the nearest tenth) 12.9
