Answer:
8
Step-by-step explanation:
use trig functions
2 sides and 1 angle given
Sides given
Angle
trig function associated with hyp and opp is sin
sin(x) = opp/hyp
substitute
sin 30˚ = 4/x
solve for x
0.5 = 4/x
0.5x = 4
x = 8
sin 30° = [tex]\frac{4}{x}[/tex]
x = [tex]\frac{4}{sin 30}[/tex]
x = [tex]\frac{4}{0.5}[/tex]
