    Answer:

    10

    Step-by-step explanation:

    Tan18=x/30

    .3249 x 30 = 9.747 x = 9.7, but to the nearest meter will be 10.

    Answer:

    10\:\mathrm{meters}

    Step-by-step explanation:

    We can use trigonometry for a right triangle to solve this problem:

    \tan 18^{\circ}=\frac{h}{30},\\h=30\cdot\tan 18^{\circ},\\h\approx \fbox{$10\:\mathrm{m}$}.
