Work: Calculate the value of equation 60^2+146^2-2*60*146*cos(134) .
Question type: Mathematical calculation
Solution:
60^2+146^2-2*60*146*cos(134)
=60^2+146^2-2*60*146*cos134
=60^2+146^2-2*60*146*-0.463829
=3600+146^2-2*60*146*(-0.463829)
=3600+21316-2*60*146*(-0.463829)
=3600+21316-120*146*(-0.463829)
=3600+21316-17520*(-0.463829)
=3600+21316-(-8126.28408)
=24916-(-8126.28408)
=33042.28408
Answer:60^2+146^2-2*60*146*cos(134)=33042.28408
