Step-by-step explanation:
In the first series, the summation applies to the whole (2n+3) inside
the parentheses, so the 3 gets summed up 5 times.
But in the second one, the summation only applies to the 2n , so
the 3 is only added after the summation is finished.
The difference between five 3s the first time and one 3 the second time
is your 12 .
The total amount of angles in quadrilateral is 360.so:
z=360-(122+79+90)
z=360-291
z=69
