Step-by-step explanation:


Given the information above, we can simply set up an equation so we can find the value of x.

Subtract 42 on both sides.

Divide 14 on both sides.

So, the value of x is equal to -1/2 when f(x) is 35.
Area=(Theta/2) * r^2 This should be it, obviously Theta is your angle and you should use radiants in theory.
