To solve this
problem, we must remember that the sum of interior angle of a polygon is:
Sum of
interior angles = (n – 2) * 180˚
So, we can say
that:
Sum of
interior angles = angle A + angle B + angle C + angle D = (4 – 2) * 180˚
Where,
angle C + angle
D = 110 + 70 = 180˚
Therefore
substituting this value:
angle A + angle
B + 180˚ = 2 * 108˚
angle A + angle
B = 360˚ - 180˚
angle A + angle
B = 180˚ (answer)
Hence we can
also conclude that,
<span>angle A + angle
B = angle C + angle D</span>
Answer:
When n=1, there is 1 dot. When n=2, there are 3 dots. When n=3, there are 6 dots. so when n=1 the eqaution would show as when sloving this combin the like terms in the parenthesis so 1+1 =2 and 1*2 = 2 when that is divided it equals 1.
