h =  \frac{2f}{m} + 1 \\ \\ mh = 2f + 1  (re-arranged) \\ \\ mh - 1 = 2f \\ \\ f =   \frac{(mh - 1)}{2}

H=2f/m+1
subtract one from both sides
h-1=2f/m
multiply m to both sides
m*h-1=2f
divide 2 both sides
mh-1/2=F
(the whole left side of the equation is divided by 2 i just cant do it on the computer)

Two submarines, one cruising at 25 knots and the other at 20 knots, left a naval base at the same moment. Three hours later, the
sweet [91]
<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

                               cosB=\frac{a^2+c^2-b^2}{2ac}

                               a = 86.31 miles

                               b = 115.08 miles  

                               c = 69 miles  

Substituting

                cosB=\frac{86.31^2+69^2-115.08^2}{2\times 86.31\times 69}\\\\cosB=-0.0867\\\\B=94.98^0=95^0

Measure of the angle between their courses  is 95°
