Answer:AB=15 ,angle A=53.1°,angle B=36.9°
Step-by-step explanation:
AB=√(12^2+9^2)
AB=√(12x12+9x9)
AB=√(144+81)
AB=√(225)
AB=15
TanA=12/9
TanA=4/3
A=Tan(inverse)(4/3)
A=53.1° angle A=53.1°
angle B=180-(90+53.1)
angle B=180-143.1
angle B=36.9°

Answer: 72 units^2
Explanation:
Triangle to the left, you do 5(6) and get 30, but since it's a triangle, you divide by 2 and get 15. Middle rectangle, 6(8) is 48. Right triangle, 3(6) is 18, 18/2 is 9. Add them all up 15+48+9 and you get 72. Hope this helped!
Answer:
234 miles a day
Step-by-step explanation:
<em><u>The whole trip was for 2 weeks (7*2=14 days).</u></em>
<em><u>Since 1 day from each week they took rest, they drove for (14-2(1)=12 days) 12 days.</u></em>
So a total of 2808 for 12 days. The average is 2808 divided by 12 days:

The answer is 234 miles a day
