Step-by-step explanation:I subtracted the two numbers because one was negative, but the answer still remains positive because the highest absolute number is positive.
The actual speed of the plane with the wind: v² = ( 150 + 50 · cos 45°)² + ( 50 · sin 45°)² v² = ( 150 + 35.355 )² + 35.355² v² = 34,356.467 + 1,249.976 v = √35,606.452 v = 188.7 mph
