Answer:
m<BCA+m<BCD=180
Step-by-step explanation:
supplementary means that the angle measures add up to 180°, if you are using the definition of supplementary angles AND you have had a statement saying that two angles are supplementary, ALWAYS follow it with the sum of the measures of those angles equal 180 :)
10, because when you use a scientific calculator you get 10.09950494
which would be round to 10 because after the decimal the number is 0 below 5 so 10 stays as 10
Plugging in the values, we get 7(6)-4=42-4=38.
D. $2,458*12=29,496*8=$235,968 and then the closest number above that bc its between 8-10 times not 7-8 or 6-8 or something like that.
