<h2>
Measure of the angle between their courses is 95°</h2>
Step-by-step explanation:
Speed of submarine 1 = 25 knots = 28.77 mph
Speed of submarine 2 = 20 knots = 23 mph
Time taken = 3 hours
Distance traveled by submarine 1 = 28.77 x 3 = 86.31 miles
Distance traveled by submarine 2 = 23 x 3 = 69 miles
Distance between them is 100 nautical miles = 115.08 miles
Refer the figure
By cosine formula we have

a = 86.31 miles
b = 115.08 miles
c = 69 miles
Substituting

Measure of the angle between their courses is 95°
We know the angles Q=Sand the sides QR=ST, because PRT is on a line we know the angle <PRQ=<RTS, so it should be ASA
