Ответ:
c^2 = a^2 + b^2 - 2 * a *b *cos(Y)
250^2 = 160^2 + 260^2 - 2 *160 * 260 * cos(Y)
62500 = 25600 + 67600 - 83200 * cos(Y)
83200 * cos(Y) = 25600 + 67600 - 62500
83200 * cos(Y) = 30700
cos(Y) = 307/832
Y = arccos(307/832)
Y = 68.35
X = 180 - 68.35
X = 111.65
The answer is B.

Convection currents are created in the Earth's atmosphere as the sun heats the gases, causing them to rise. Theses gases cool as they rise high into the atmosphere and travel back down towards the ground to get heated again. ... All of this movement of gases in the atmosphere creates wind.
