Answer:
12.9
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
