Question

For Tran thank you appreciate it

Answer 1

Explanation:

Let alpha be the unknown angle. We can set up our sine law as follows:

`( \sin( \alpha ) )/(5 \: m) = ( \sin(42) )/(3.6 \: m )`

or

`\sin( \alpha ) = (5 \: m)/(3.6 \: m) * \sin(42) = 0.929`

Solving for alpha,

`\alpha = arcsin(0.929) = 68 \: degrees`
