Answer:

x ≈ 136.7 ft

Explanation:

As you have marked, the relevant sides are the adjacent side and the hypotenuse. The mnemonic SOH CAH TOA reminds you ...

Cos = Adjacent/Hypotenuse

For this triangle, that means ...

cos(43°) = (100 ft)/x

x = (100 ft)/cos(43°) . . . . . . . . . . multiply both sides by x/cos(43°)

x ≈ 136.73 ft

The length x is about 136.7 feet.
