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!
