Question

Can someone help me please and thxxx

Answer 1

Answer:

x = $8\sqrt{3}$

y = $4\sqrt{3}$

Step-by-step explanation:

• tan 60° = 12/ y         [tan θ = opposite/ adjacent]

y = 12/ tan 60°  

y = $4\sqrt{3}$

• x² = y² + 12²             [Pythagoras's theorem]

x² = ( $4\sqrt{3}$ )² + 144

x = $\sqrt{(4\sqrt{3})^{2} \space\ + \space\ 144}$

x = $8\sqrt{3}$

Answer 2

Answer:

C

Step-by-step explanation:

cos 30=12/x

$x = 8 \sqrt{3}$

cos60=y/x

$y =4 \sqrt{3}$
