Round to the nearest hundredth.
Solution
Solution Steps
Step 1: Identify the given information
We are given a right triangle with the adjacent side to angle \(x\) as 3 cm and the hypotenuse as 5 cm.
Step 2: Choose the correct trigonometric ratio
We can use the cosine ratio, which relates the adjacent side and the hypotenuse to the angle.
\[\cos(x) = \frac{\text{adjacent}}{\text{hypotenuse}}\]
Step 3: Substitute the given values
Substituting the given values into the cosine ratio, we get:
\[\cos(x) = \frac{3}{5}\]
Step 4: Solve for x
To find \(x\), we need to take the inverse cosine (arccos) of both sides:
\[x = \arccos\left(\frac{3}{5}\right)\]
Using a calculator, we get:
\[x \approx 53.13^\circ\]
