Answer:
138 degrees
Step-by-step explanation:
I'm assuming you meant measurement of angle 1 = 42 degrees.
If d//m, then angles 1,4,5, and 8 all have to have the same angle measurement. Likewise, angles 2,3,6, and 7 all have to have the same angle measurement.
So, because we know the angle measurement of angle 1, we can use that to calculate angle 2. Because angle 1 + angle 2 = 180 degrees, we can just do 180 - angle 1 to calculate the measurement of angle 2, which would be 138 degrees. Because angle 2 and angle 7 have to be the same measurement in order to have d//m, angle 7 must be 138 degrees.
We know that 1 lb = 16 oz
So lets convert the 20 lb to oz and then compare the two quantities in consistent units.
If 1 lb = 16 oz then 20 lb are equal to 20*16 oz, that is
20 lb = 20*16 oz = 320 oz
therefore,
320 oz are greater than 272 oz, or,
20 lb are greater that 272 oz
Yo sup??
we should know that negative*negative=positive
(4+7*8/7)*(3+4)
=60/7*7
=60
Hope this helps
Answer: the answer is A
Step-by-step explanation:
The total cost of her haircut was 28 dollars
step by step:
(percentage) 15 x 6 = 90
4.20 x 6 =25.2
(perscentage) 15 divided by 3 = 5
4.20 divided by 3 = 1.4
1.4 + 1.4 = 2.8
25.2 + 2.8 =28
