ABCD is a trapezium in which : AD // BC , m (< B) = 90°
If AB = 4 cm.
AD = 7 cm. , BC = 10 cm.
» prove that : cos (< DCB) – tan (< ACB) = 1:5​

Step-by-step explanation:

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

yes because they have the same amount of green and blur marbles.
