Answer:
The answer to your question is 2.8 x 10¹¹
Step-by-step explanation:
Data
1 tree produces 2.6 x 10² pounds of oxygen/year
number of trees = 3.9 x 10¹¹
pounds of oxygen per day = ?
Process
1.- Divide the pounds of oxygen by 365, to get the pounds of oxygen per day.
2.6 x 10² / 365 = 0.712
2.- Multiply the number of trees by the pounds of oxygen per day
3.9 x 10¹¹ x 0.712 = 2.8 x 10¹¹ pounds of oxygen

Answer:
adjacent angles
complementary angles
Step-by-step explanation:
vertical angles are across from each other and equal False
adjacent angles are next to each other True
Complementary angles add to 90 degrees ( If next to each other , they form a right angle) True
Supplementary angles. add to 180 degrees, ( if next to each other, they form a straight line) False
