T(t)T, models the daily high temperature (in Celsius) in Santiago, Chile, t days after the hottest day of the year. Here, t is entered in radians.

T(t)=7.5cos(2π/365t)+21.5

What is the second time after the hottest day of the year that the daily high temperature is 20 degrees celsius?

Round your final answer to the nearest whole day.

the answer is 262 days

Step-by-step explanation:

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

may i see the picture? it would a lot, xox
