Question

-50√3 tg 420(градусов)

Answer 1

50*√3tg(360+60) = 50*√3tg60 = 50*√3*√3 = 50*3 = 150
Ответ: 150

Answer 2

To calculate the value of the expression, we need to evaluate each part separately.

1. -50√3: This simply means -50 multiplied by the square root of 3. -50√3 ≈ -50 * 1.732 ≈ -86.60

2. tg 420°: "tg" represents the tangent function, and 420 degrees is an angle in the trigonometric circle.

Keep in mind that 360 degrees is one full revolution in a circle, so 420 degrees is the same as 420 - 360 = 60 degrees (as they are coterminal angles).

The tangent function of 60 degrees can be calculated as follows:

tg(60°) = tan(60°) = √3 ≈ 1.732

So, putting it all together:

-50√3 tg 420° ≈ -86.60 * 1.732 ≈ -150.08

Therefore, the approximate value of the expression is -150.08.
