So,
The critical points of 
Answer:
840
Step-by-step explanation:
I=PRT
I =4000 x 0.07 x 3
I=840
Since you have the 42-deg angle and the length of the opposite side, 31, you can use the Law of Sines.

We will use the law of sines first to find x.
Once we know x, we can find the angle opposite y.
Then we can find y.




Let z = the angle opposite y.
z + 42 + 53 = 180
z = 85
