Answer:
A measures 72 and B measures 108
Step-by-step explanation:
If the angles are supplementary, that means that they add up to equal 180. 3x + 12 + 4x + 28 = 180. Doing some algebra there gives you that 7x = 140 and x = 20. Sub in 20 to angle A to get 3(20) + 12 = 72, and sub in 20 to angle B to get 4(20) + 28 = 108. And of course, 108 + 72 = 180.
Answer:
8.2 hours
Step-by-step explanation:
Since Joe started his trip driving an average speed of 50 miles per hour, you would have to divide 410 and 50. You would get the answer of 8.2 hours
1. (3,-2)
2. (-5,-4)
3. (-20,11)
4. (2,3)
5. (13/7, 40/7)
Answer:
50
Step-by-step explanation:
3x = 25 - 5y
-100 < 5y < 50
-50 < -5y < 100
-25 < 25 - 5y < 125
-8.333 < x < 41.667
41+8+1 = 50
45 degree between Oak street and Elm Street.
