EXPLANATION
Given the right triangle, applying the Law of Sines give us the unknown measure:
[tex]\frac{29}{90}=\frac{x}{19}[/tex]
Multiplying both sides by 19:
[tex]19\cdot\frac{29}{90}=x[/tex]
Multilplying the fractions:
[tex]\frac{551}{90}=x[/tex]
Switching sides:
[tex]x=\frac{551}{90}=6.12\approx6.1[/tex]
The answer is x=6.1 units
