Cos(angle) = Adjacent Leg / Hypotenuse
cos(35) = 9 / x
x = 9 / cos(35)
x = 10.99
Rounded to nearest tenth = 11.0
The length would be:
120-2(20)=2x
Then you would solve for x.
120-40=2x
80=2x
x=40, so the length is 40 yards.

x²+2x-5=0

Answer:
x = 1
Step-by-step explanation:
Given
← factor numerator and denominator
=
← cancel (x - 4) on numerator/ denominator
=
The denominator of the rational expression cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that x cannot be.
x - 1 = 0 ⇒ x = 1 ← excluded value
