Answer:
EFG = 50.6, LMN = 129.4
Step-by-step explanation:
ok so s supplementary angles mean, their angles will always add upto 180. for example if one angle is 100° then the other will be 80°.
to find the angles first we need to solve for x. 
we know EFG + LMN = 180 because its supplementary.
that's is (3x+17) + (12x-5) = 180.
we now solve for x;
15x+12 = 180
15x = 168, x= 168/15 = 11.2
now that we know x we can put this value in the corresponding equation of EFG and LMN to find the angles.
EFG = 3x11.2 + 17 = 50.6
LMN = 12x11.2 - 5 = 129.4

Answer:
<h2>61°</h2>
Step-by-step explanation:
Use the sine law:

We have:

Substitute:
 <em>cross multiply</em>
         <em>cross multiply</em>

 <em>divide both sides by 6</em>
          <em>divide both sides by 6</em>
