Answer :

Answer:

C

[tex]\frac{30}{\cos25}[/tex]

Explanation:

Given the image of the right angle, to find PQ, we have to take the cosine of angle 25 degrees as shown below;

[tex]\cos 25=\frac{30}{PQ}[/tex]

Let's go ahead and make PQ the subject of formula;

[tex]\begin{gathered} PQ\cos 25=30 \\ PQ=\frac{30}{\cos25} \end{gathered}[/tex]
