Answer:
x=31.67[by rounding]
Step-by-step explanation:
As
sin=p/h
Here,
p=2.1
h=4
[tex]solution \\ sin(x )= \frac{2.1}{4} \\ sin(x) = 0.525 \\ \sin(x) = sin(31.66824325 )\\ x = 31.66824325[/tex]
Answer:
31.7°
Step-by-step explanation:
[tex]sin(x)=\frac{opposite}{hypotenus} \\x = sin^{-1} (\frac{2.1}{4} )\\x = 31.668 = 31.7(nearest\ tenth\ of\ a\ degree)[/tex]
