Question

4*5*sin(60)= Peшите пожалуйста

Answer 1

sin60 = √3/2(по таблице), значит, 4*5*√3/2 = 20/1 * √3/2=20√3/2. Вроде так.

Answer 2

Calculation of 4*5*sin(60)

To calculate the value of 4*5*sin(60), we can break it down step by step.

First, we calculate the sine of 60 degrees, which is a standard trigonometric value.

Sine of 60 degrees: Using the trigonometric values of common angles, the sine of 60 degrees is equal to 0.86602540378.

Now, we can multiply this value by 4*5 to get the final result.

Calculation: 4 * 5 * sin(60) = 4 * 5 * 0.86602540378 = 17.3205080756

Therefore, the value of 4*5*sin(60) is 17.3205080756.

This calculation is based on standard trigonometric values and multiplication.
