Answer:
x = 10
Step-by-step explanation:
note that sin30° = [tex]\frac{1}{2}[/tex]
Since the triangle is right use the sine ratio to find x
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{5}{x}[/tex]
multiply both sides by x
x × [tex]\frac{1}{2}[/tex] = 5 ( multiply both sides by 2 )
x = 10
