Question

2cos60-3tg45..........​

Answer 1

Ответ: -2

Объяснение:

2 cos 60 - 3 tg 45=2*0.5-3*1=1-3=-2

cos 60=0.5

tg 45=1

Answer 2

Let's calculate the expression 2cos(60) - 3tan(45):

1. cos(60°) is equal to 0.5. This is because the cosine of 60 degrees is one-half or 0.5.
2. tan(45°) is equal to 1. This is because the tangent of 45 degrees is always 1.

Now, plug these values into the expression:

2 * 0.5 - 3 * 1

Now, perform the calculations:

1 - 3 = -2

So, 2cos(60) - 3tan(45) is equal to -2.
