Pretty sure the equation is: y=2x+4
I’m pretty sure you are supposed to use the law of sine, which states A/sin(a)=B/sin(b)=C/sin(c), where A is the side opposite of angle A. Number 4 would be28/sin37=x/sin49, solving for x. I do not have a calculator with me but I hope this helps

Prove that the formula works, when n=k+1

Since the formula has been proven with n=1 and n=k+1, it is true.
