Answer:
15+3=18 years
Step-by-step explanation:
Since the black bear lives 3 years longer than the zebra, all it really means is 3 additonial year so you add 3 on to the 15.
N=4, because 9x-3=-27, the absolute value of -27 is 27. Then you add 3 to 105 and get 108 then devide by 27 giving you 4.

We know that the interior angles of a trapezoid add up to 360 degrees.
Write out an equation to represent this situation;
108+108+2x+2x=360
216+4x=360
4x=360-216
4x=144
x=144/4
x=36
Therefore, the measure of x is 36 degrees.
