Answer:
Step-by-step explanation:
The side opposite the given width of x is also x.
So you have to relate 3 facts.
The angle
The adjacent side
The hypotenuse.
Formula
Cos(28) = x / 35
Solution
Cos(28) = x / 35 Multiply both sides by 35
35 cos(28) = 35 * x / 35 Cancel
35 cos(28) = x Multiply
30.90 = x
Rounded, it is 30.9
