Answer:
i think this might be right im sorry if its not but heres an explantion i have.
Explanation:
72 is on the bottom left and it would also be on the bottom top so we know both of those corners angle degrees, so add 72+72 and we et 144. then the total area is equal to 360, so subract 144 from 360 and we get 216. after that we apply the first equation- f+30=216, subract 30 and we get f= 186, but you see that we have two corners with the same angle again so 186 divided by 2 and we get that f = 93.
as for solving for g, we know that the other side length is 25 and these sides are parallel, so 8g-3= 25. add 3 to 25 and we have 8g = 28, divide by 8 and we get that g = 3.5.
i hope this is right and i hope it may help! good luck on the rest!!
