Question

find the trig ratio. cos(θ) = ? enter as a decimal. round to the nearest hundred

Explanation:

Step1: Recall the cosine formula

In a right - triangle, \(\cos(\theta)=\frac{\text{adjacent}}{\text{hypotenuse}}\).

Step2: Identify adjacent and hypotenuse

The adjacent side to \(\theta\) is \(21\), and the hypotenuse is \(29\).
So, \(\cos(\theta)=\frac{21}{29}\).

Step3: Calculate the decimal value

\(\frac{21}{29}\approx0.72\) (rounded to the nearest hundredth).

Answer:

\(0.72\)
