Answer:
C
Step-by-step explanation:
cos 30=12/x
[tex]x = 8 \sqrt{3} [/tex]
cos60=y/x
[tex]y =4 \sqrt{3} [/tex]
Answer:
x = [tex]8\sqrt{3}[/tex]
y = [tex]4\sqrt{3}[/tex]
Step-by-step explanation:
• tan 60° = 12/ y [tan θ = opposite/ adjacent]
y = 12/ tan 60°
y = [tex]4\sqrt{3}[/tex]
• x² = y² + 12² [Pythagoras's theorem]
x² = ( [tex]4\sqrt{3}[/tex] )² + 144
x = [tex]\sqrt{(4\sqrt{3})^{2} \space\ + \space\ 144}[/tex]
x = [tex]8\sqrt{3}[/tex]
