Step-by-step explanation:
The law of cosines can be used to solve such problems. It relates sides a, b, c and angle A as follows:
a^2 = b^2 + c^2 -2bc·cos(A)
Using b=250, c=360, and A=34°, we get
a^2 = 250^2 +360^2 -2·250·360·cos(34°)
a^2 ≈ 48,873.24
a ≈ 207.06
The distance between the other two subs is about 207 meters.
