Hi there! Thanks for your questions ;)

The answers are quite easily, go through the steps below so that you can catch it up yourself!!

a)

=
$\rm{sin (x) = (9)/(20)}$

=
$\rm{0.45}$

=
$\rm{x = arcsin(0.45)}$

=
$\rm{26.74 \: degrees}$

(b)

here, h is height.

=
$\rm{h = 20 * cos(x)}$

=
$\rm{20 * cos(26.74)}$

=
$\rm{ 17.86 \: m}$

Hope it is helpful!
