Answer:
90°
Step-by-step explanation:
EG is a straight line
EG = EHD + DHG
DHG is a 90 degree angle
180 = EHD +90
Subtract 90 from each side
180-90= EHD +90-90
90 = EHD
The arc has the same measure as the angle since it is from the center
arc ED = 90
Answer C
steps
deduct 10 from 26
26-10 which will give us 16
The number of batches Nathaniel can make is 16.5 batches.
Nathaniel plans to make use of less than 40 cups of flour and he has already used 6 cups of flour. In order to determine how many batches he can make, we have to determine the number of cups of flour he can use. The cups of flour would be divided by the amount of flour that can be used to make a batch of muffins.
Maximum amount of flour Nathaniel can use = 39 - 6 = 33
Number of batches he can make = 33 / 2 = 16.5 batches
