Question

4sin30°+6 cos 60°-tg 45°​

Answer 1

Ответ:

4.

Объяснение:

sin 30° = 1/2

cos 60° = 1/2

tan 45° = 1

4sin30° + 6cos60° - tan45°

= 4(1/2) + 6(1/2) - 1

= 2 + 3 - 1

= 4

Answer 2

To solve the expression 4sin30° + 6cos60° - tg45°, let's evaluate each trigonometric function separately:

1. sin 30°: The sine of 30 degrees is equal to 0.5. sin 30° = 0.5

2. cos 60°: The cosine of 60 degrees is equal to 0.5. cos 60° = 0.5

3. tg 45°: The tangent of 45 degrees is equal to 1. tg 45° = 1

Now, substitute the values into the expression:

4sin30° + 6cos60° - tg45° = 4(0.5) + 6(0.5) - 1 = 2 + 3 - 1 = 4

Therefore, 4sin30° + 6cos60° - tg45° is equal to 4.
