Answer:
a) 
b) 12.72 units
Step-by-step explanation:
Recall that the sine and cosine are completed functions.
This means that: 


Recall that: sine ratio is opposite/hypotenuse

This implies that:



88.4*10^3 is = 88.4*10*10*10 =88400
Hope this helps! Any questions please just ask! Thank you!
B, Because to be a parallelogram it has to have two sides that are both parallel and congruent
Y = (2/3).x - 6. If y=0, then 0= (2/3).x - 6. Solve for x:
2x/3 - 6 = 0
Same denominator:
(2x - 18)/3 = 0
2x - 18 = 0
2x = 18 and x = 9 (x-coordinate)
