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: t = - 5 ∈
= ( -∞ , -4 )
Step-by-step explanation:
The standard form of O.D.E is written as :
+ 
Equation given :
+
=
, 
The first thing to do is to write the O.D.E in standard form , that is we will divide through by
, so we have

With this , we can see that
and
are both continuous in the same domain. Therefore , the intervals are :
= ( -∞ , -4 )
= ( - 4 , 4 )
= ( 4 , -∞ )
recall that y(−5) = 1 , then t = -5
This means that :
t = - 5 ∈
= ( -∞ , -4 )
Patrick worked 160.5 hours because you have to subtract 1000 from 7420 then divide that by 40 for your answer. Also, Patrick has a sweet job.
