Use law of cosines
o^2=p^2+q^2-2pqCos(C)
o^2=38^2+29^2-38*29Cos(39)
o^2=1444+841-1712.83
o^2=572.17
o=23.92
Say 24 cm
The velocity or speed of the kayaker going north at a speed of 3 m/s and that of the current going east at a speed of 2 m/s create a resultant speed of √13 m/s. The new distance that has to be traveled by the kayaker in order to move 100 m north is calculated through the equation,
3 / √13 = 100 / x
The value of x is 120 m. The total time it will take for the kayaker to reach the destination is,
t = 120 / √13 = 33.33 s
Cos N = 3/5
Sin N = 4/5
Tan N = 4/3
Sin P = 9/15 or 3/5
Cos P = 12/15 or 4/5
Tan P = 9/12 or 3/4
