There are chemical reactions that take place within a cell?
Metabolism, the sum of the chemical reactions that take place within each cellof a living organism and that provide energy for vital processes and for synthesizing new organic material.
In quadrilateral ABCD, angle BAD and angle CDA are trisected as shown. What is the degree measure of angle AFD?
Answer: AFD = 80 Explanation: 110 + 100 + 3x + 3y = 360 210 + 3x + 3y = 360 3x + 3y = 150 3(x + y) = 150 x + y = 50 Now look at polygon ABCDF (5 sided polygon) 100 + 110 + x + y + Angle F = 540 210 + 50 + angle F = 540 260 + angle F = 540 Angle F = 280 And: angle F + AFD = 360 degree 280 + AFD = 360 AFD = 80
