Question

ROUND TO THE NEAREST WHOLE NUMBER 5) 32 35 23 7) 60

Answer 1

To find the angle we need to use the cosine function defined as:

`\cos \theta=\frac{\text{adj}}{\text{hyp}}`

For triangle 5 we notice that the adjacent leg is 23 and the hypotenuse is 32, plugging this values into the equation above and solving for theta we have:

`\begin{gathered} \cos \theta=(23)/(32) \\ \theta=\cos ^(-1)((23)/(32)) \\ \theta=44 \end{gathered}`

Therefore the missing angle is 44°
