Step-by-step explanation:
282
Step-by-step explanation:
C=180-112=68
A=180-68-51=61
sum of exterior angles=112+119+51=282
5 2/5 would be converted to 5 6/15. you would then subtract the numerators and the whole numbers, giving you 3 5/15, which simplifies to 3 1/5
% = (Change/Original) * 100
= (6/24) * 100
= (0.25) * 100
= 25%
