Sagot :

In triangle QRS, QS=7 units and angle R is 49 degrees.

To find RS use the ratio of sin as follows:

[tex]\begin{gathered} \sin 49=\frac{QS}{RS} \\ RS=\frac{QS}{\sin 49} \\ RS=\frac{7}{0.754709} \\ RS=9.2750909 \\ RS\approx9.3 \end{gathered}[/tex]

Hence the value of RS is 9.3 rounded to 1 decimal place.
