Because the two angles on the right add to 180 degrees, we can create this system:

We can also prove that 

, which, when solved, shows that 

. 
When plugged in to the original equation, we find that y = 105 degrees.

Answer:
$1,500,000
Step-by-step explanation:
Given
Principal = $1,000,000
Rate = 5%
Time = 10years
Interest = PRT/100
Interest = 1000000*5*10/100
Interest = 100000*5
Interest = $500,000
Amount after 10years =  $1,000,000+ $500,000
Amount after 10years = $1,500,000

Answer:
   103°
Step-by-step explanation:
The law of sines tells you ...
   sin(C)/c = sin(A)/a
   sin(C) = (c/a)sin(A)
   C = arcsin(c/a·sin(A)) = arcsin(37/19·sin(30°)) ≈ 180° -76.8° ≈ 103°
Obtuse angle C is about 103°.
