Cos (A+B+C) Solution

Follow our step by step solution on how to calculate Cos (A+B+C)?

FIRST Step Consider the formula
cos(A+B+C)=(cos A⋅cos B⋅cos C)-(cos A⋅sin B⋅sin C)-(sin A⋅cos B⋅sin C)-(sin A⋅sin B⋅cos C)
Next Step Substitute values of Variables
∴ cos(A+B+C)=(0.94⋅0.87⋅0.65)-(0.94⋅0.5⋅0.29)-(0.34⋅0.87⋅0.29)-(0.34⋅0.5⋅0.65)
Next Step Prepare to Evaluate
∴ cos(A+B+C)=(0.94⋅0.87⋅0.65)-(0.94⋅0.5⋅0.29)-(0.34⋅0.87⋅0.29)-(0.34⋅0.5⋅0.65)
Next Step Evaluate
∴cos(A+B+C)=0.198988
LAST Step Rounding Answer
∴cos(A+B+C)=0.199
