I(t) models the daily solar irradiance, measured in \dfrac{\text{kWh}}{\text{m}^2\text{ -day}} m 2 -day kWh ​ start fraction, start text, k, W, h, end text, divided by, start text, m, end text, squared, start text, negative, d, a, y, end text, end fraction, on a farm, t days after the summer solstice. Here, t is entered in radians. I(t) = 1.5cos( 365 2π ​ t)+4.3I, What is the second time after the summer solstice that the solar irradiance is 5.2 \dfrac{\text{kWh}}{\text{m}^2\text{ -day}}5.2 m 2 -day kWh ​ 5, point, 2, start fraction, start text, k, W, h, end text, divided by, start text, m, end text, squared, start text, negative, d, a, y, end text, end fraction? Round your final answer to the nearest whole day.
