Question

What do you notice ?

Answer 1

x = 24.27 (rounded to the nearest hundredth)

Step-by-step explanation

We know the length of the hypotenuse and the measure of one of the interior angles, since we want to know the length of the adjacent side to this angle we have to use the cosine of the angle:

`\cos \theta=\frac{\text{adjacent side}}{hypotenuse}`

For this problem

`\begin{gathered} \cos 21º=(x)/(26) \\ x=26\cos 21º \\ x\approx24.27 \end{gathered}`
