Question

Cos60o+0,5 (tg45o-0,5)

Answer 1

Ответ:

cos60°+ 0,5(tg45°- 0,5 ) = 0,5 + 0,5×0,5 = 0,75

Answer 2

To solve the expression, let's break it down step by step:

1. Cosine of 60 degrees (Cos 60°): Cos 60° is equal to 0.5.

2. Tangent of 45 degrees (Tan 45°): Tan 45° is equal to 1.

3. 0.5 times (1 - 0.5): This is equivalent to 0.5 * 0.5 which is 0.25.

Finally, add the results:

0.5 (1 - 0.5) = 0.25

So, the final result is 0.25.
