The given triangle is a right angle triangle. Considering angle 18 as the reference angle,

x = hypotenuse

29 = adjacent side

We would find the hypotenuse, x by applying the cosine trigonometric ratio which is expressed as

Cos# = adjacent side/hypotenuse

Thus, we have

Cos18 = 29/x

29 = xCos18

x = 29/Cos18 = 29/0.95

x = 30.53
