or the third down from the top. Count the sides and multiply by how many layers
Answer:
14x+30y-20
Step-by-step explanation:
14(x+y)=14x+14y
14y+y=15y+15y=30y
and there is no like terms for -20 and 14x so the answer is
14x+30y-20
I say the answer is B. Bland
Since AED forms a straight line, all involved angles sum to 180°. Therefore AEB + BED = 180. Also, since EC bisects BED, BEC = CED, and BED = 2× CED. Now to substitute the first equation:
AEB + BED = 180
AEB + 2×CED = 180
11x-12 + 2(4x+1) = 180
11x-12+8x+2 = 180
19x-10 = 180
19x-10+10 = 180+10
19x = 190
x = 10
So what is m<AEC?? It is the sum of AEB + BEC, and since BEC = CED we can say that:
AEC = AEB + CED
AEC = 11x-12 + 4x+1 = 15x-11 = 15(10)-11 = 150-11
m<AEC = 139°
