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>
The answer is C, trust me.
Answer:
21.7
Step-by-step explanation:
by Pythogorean theorm= 27^2 -16^2=x^2
x^2=729-256
x^2=473
x=√473
x=21.7
Answer:
Present value of contributions is $24,106.15
Step-by-step explanation:
Weekly rate=9%/52weeks= 0.173%
Weekly contributions $50
Number of weeks=20years×52weeks=1040
Present value of contribution=$50(1-[(1+9%/52)^-1040 /(9%/52)
Present value of contribution= $24,106.15
