Question

6cos60-2ctg45°*sin45°
* - умножить
° - градусы​

Answer 1

Ответ:

$6cos60^{circ} - 2ctg45^{circ} cdot sin45^{circ} = 3 - sqrt{2}$

Объяснение:

$cos60^{circ} = frac{1}{2}$

$ctg45^{circ} = 1$

$sin45^{circ} = frac{sqrt{2}}{2}$

$6cos60^{circ} = 3$

$2ctg45^{circ} cdot sin45^{circ} = 2 cdotfrac{sqrt{2}}{2} = sqrt{2}$
