An airplane started at point K, travelled 560 miles to point L, adjusted its route and travelled another 575 miles to point M. I
S_A_V [24]

Answer:

Step-by-step explanation:

Using the cosine theorem:

c^{2} =a^{2} +b^{2} -abcos\beta

952^{2} =560^{2} +575^{2} -560*575cos\beta

\beta =cos^{-1} (\frac{560^{2}+575^{2}-952^{2}   }{2*560*575} )

The angle is 114.014 degrees if we substract 90 degrees it means that at point L the plane changed its angle by 24 degrees
