117 degrees
The angles in a trapezoid add up to 360 degrees. 63 x 2 = 126
360 - 126 = 234
234/2 = 117
The answer is a all of the points
The answer is 6t^2+2.5x^2-0.5t-5.4
We presume the temperature is decreasing at midnight, so reaches a low at 6 a.m.. The amplitude of the variation is (87-63)/2 = 12 degrees. We want the period to be 24 hours, so the argument of the sine function will be 2π(t/24) = πt/12. Then we can write
... d = 75-12sin(π·t/12)
