Help appreciated tyty​

Answer 1

Answer:
`\text{x} = 6√(3)`

Work Shown

`\cos(30^(\circ)) = \frac{\text{x}}{12}\\\\(√(3))/(2) = \frac{\text{x}}{12}\\\\(6√(3))/(6*2) = \frac{\text{x}}{12}\\\\(6√(3))/(12) = \frac{\text{x}}{12}\\\\\text{x} = 6√(3)\\\\`

Use the unit circle or a trig reference sheet to determine that cos(30) = sqrt(3)/2, or this is something to memorize because it comes up a lot in trig.
