Answer:
angle 1 = 83°
angle 2 = 88°
Step-by-step explanation:
angle 1 and angle on vertex B are
pair of co interior angles ( whose sum = 180° )
so, angle 1 + angle B = 180°
angle 1 = 180° - angle B
angle 1 = 180° - 97° = 83°
hence, angle 1 = 83°
but, angle 2 and exterior of vertex A forms alternate interior angle pair ,
so , angle 2 = angle A = 88°
i hope you got it ....

Answer:
i really dont know the answer
Step-by-step explanation:
Let
The exponent is indeed 
- not a typo!
Take the antiderivative of 
, denoted by 
. This recovers a factor of 
in the denominator, which lets us condense it to a single factorial.
Recall the series expansion of sine,
Then with a little algebraic manipulation, we get
Differentiate to recover .
Finally, 
, so our sum is
