We can use SOH CAH TOA to solve this :)

We’re going to use Cosine because the angle and sides given are Adjacent and Hypotenuse- which goes with the CAH part of SOH CAH TOA.

Cos(18) = x/25

Multiply both sides by 25

25cos(18) = X = 23.776

So x = 23.776 cm

I hope this Helps!
You would multiply the sides of the triange by 25.

And that gives you...  x = 23.776 cm
