Question

Solve for the missing angle. Round to the nearest hundredth.18?13? =degrees

Answer 1

43.76 degrees.

Step-by-step explanation:

The trigonometric function cosine relates the adjacent side with the hypotenuse. Therefore, we can find the missing angle using the following equation:

`\text{cos}\theta=(Adjacent)/(Hypotenuse)`

So, replacing the values, we get:

`\cos \theta=(13)/(18)=0.7222`

Therefore, the missing angle is:

`\begin{gathered} \theta=\cos ^(-1)((13)/(18)) \\ \theta=43.76 \end{gathered}`

Then, the missing angle has a measure of 43.76 degrees.
