Question

I need help txt bck quickly please

Answer 1

With respect to the 20 degree angle, x is the opposite side, and 9 is the adjacent side, so use the tangent ratio (tan = opp / adj)


`(x)/(9)=\tan 20 \\ x=9\tan 20`

Use a calculator (in degree mode!) to find a decimal for the answer.

Answer 2

9 x tan(20) = 3.2757

so 3.3
