1) In this problem, we can find the leg by first finding the interior upper angle of that triangle.
2) Note that we can sketch this out and find the missing angle:
We can see that that upper angle is complementary.
So now, let's use a trig ratio so that we can find the opposite leg to angle 61º:
![\begin{gathered} \sin (61^(\circ))=(x)/(500^(\square)) \\ x=500\cdot\sin (61^(\circ)) \\ x\approx437.3 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/xn1p5pba2w9c8kord1lnic43sx0guv14ju.png)
Thus this is the answer
