Answer:
180° is the correct answer. Hope this helped :)
Step-by-step explanation:
180°
a convex polygon has n sides, then its interior angle sum is
S = ( n −2) × 180°
S=(3-2)*180°=180°
1/(4a) & 5/(6a)
(3)(1/4a)=3/12a
(2)(5/6a)=10/12a
LCD=12a
b
18+2x
6-4(2x-3)+10x
6-8x+12+10x multiply 2x-3 by -4
18+2x combine like terms
