Answer:

The correct option is c.

Step-by-step explanation:

From the given figure it is noticed that the triangle PQR is a right angle triangle.

In a right angle triangle,

[tex]\sin\theta=\frac{perpendicular}{hypotenuse}[/tex]

In triangle PQR,

[tex]\sin R=\frac{PQ}{QR}[/tex]

[tex]\sin R=\frac{37}{58}[/tex]

[tex]R=\sin^{-1}(\frac{37}{58})[/tex]

[tex]R=39.6377144^{\circ}[/tex]

[tex]R\approx 39.6^{\circ}[/tex]

Therefore option c is correct.
