Question

Find the Value for x

Answer 1

x is the opposite side of the 30 degrees angle and 12 is the adjacent side. Utilizing trigonometry functions, recall that tan(angle)=opposite/adjacent. Thus, tan(30)=x/12. x=tan(30)*12

tan30=

`( √(3) )/(3)`
Thus x=

`12 * ( √(3) )/(3)`
or equivalently

`4 √(3)`
