Answer:
1. m∠8 = 30° 2. m∠5 = 27° 3. m∠1=m∠8 4. m∠3=m∠7
m∠6 = 180-120
m∠6 = 60
if m∠1 is 120 and m∠6 is 60, it is true because m∠2 and m∠1 are linear pairs/supplementary, so when you set them = 180 and solve for m∠2, you'll get 60. and because corresponding angles are equal and angle 6 and 2 corresponds, m∠6 will be the same measure as m∠2
Step-by-step explanation:
- because corresponding angles are equal in measure.
- because alternate interior angles are equal in measure
- because they alternate
- because they correspond
- because co-interior angles are supplementary, subtract 120 from 180 to get m∠6.
Step-by-step explanation:
14d +9 <100
14d represents cost for dvds. 9 is the flat rate shipping. all must be less than 100
The following statements in this case are correct:
1) The independent variable is t.
2) The dependent variable is f (t).
3) When f (2) = 1,323, the 2 represents "the year 2002," and the 1,323 represents "1,323 tons of garbage produced."
4) When f (4) = 1,458.6, the 4 represents "the year 2004," and the 1,458.6 represents "1,458.6 tons of garbage produced."
Note: for statements 3) and 4) the following is done:
f (2) = (1200) * (1.05) ^ 2 = 1323
f (4) = (1200) * (1.05) ^ 4 = 1458.6
