What is the measurement of angle BEC?

I think its -120 but am not sure so sorry if its wrong

Step-by-step explanation:

what makes these tough is that you have to remember that the total of the angle is known,  you know it to be 180 ° , so since you know the total just set all the part equal to that

180 = 4x + 6x-20 + 5x - 10

now you can slove for x with your mad algebra skilz  :) if you don't have those yet. it's okay.. most people don't  :D  Super hero's and math whizzes only, seem to have those.  :D

180 = 15x -30

210 = 15x

14 = x  

now that we know what x is , plug it into the angle BCE

BCE = 6(14) -20

BCE = 84 -20

BCE = 64 °

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
