3

2. We need to find the length of the adjacent side, which is labeled as $x$. We must round our answer to the nearest tenth.

2. Solution Steps

We can use the tangent function to relate the angle to the opposite and adjacent sides.
The tangent function is defined as:
tan(θ)=oppositeadjacenttan(\theta) = \frac{opposite}{adjacent}
In this case, θ=54\theta = 54^{\circ}, the opposite side is 32, and the adjacent side is xx.
So, we have:
tan(54)=32xtan(54^{\circ}) = \frac{32}{x}
Now, we can solve for xx:
x=32tan(54)x = \frac{32}{tan(54^{\circ})}
Using a calculator, we find that tan(54)1.37638tan(54^{\circ}) \approx 1.37638.
x321.3763823.249x \approx \frac{32}{1.37638} \approx 23.249
Rounding to the nearest tenth, we get x23.2x \approx 23.2.
