first use the pythagorean theorem for EG and GF so 33 squared plus 25 squared whicjh is 1714 square root it gives you approximately 41.4. or trig like soh cah toa if youve done that

or TanX-1=33/25 to find measure of angleF. then you can do law of sine to find measure of angle E can you do that?

Lol wait so it is 43.56 not 43.6? Because it says if necessary round your answer to two decimal places
