Answer:
360°
75° + 15t
Step-by-step explanation:
Given that the initial temperature of the oven is 75° and the temperature will increase at a rate of 15° per minute, it means that the temperature T after x minutes will be given as
T = 75 + 15x
Hence after 19 minutes, the temperature will be
= 75 + 15(19)
= 75 + 285
= 360°
After t minutes, the temperature will be
= 75° + 15t
(3x - 10) + 45 + (2x + 10) = 180 (the sum of the angles is 180)
3x - 10 + 45 + 2x + 10 = 180
3x + 2x = 180 + 10 - 45 -10
5x = 135
x = 27
3(27) - 10 = 71 (first angle)
2(27) + 10 = 64 (second)
45 (third)
71 + 64 + 45 = 180
