The musicians straight time pay is $107.75
(t + 12) ^ 2
(t + 12) (t + 12)
t ^ 2 + 12t + 12t + 144 144 24
t ^ 2 + 24t + 144 -------|--------
(t + 12) (t + 12) = 0 12,12 | 24
t = -12
Without using a calculator I would say the root is between 10 and 11
How I found the answer:
I know 10 * 10 = 100
I know 11 * 11 = 121
So the root of 100 = 10 and the root of 121 = 11 so that means the root of 108 is somewhere between 10 and 11, which the root of 108 = 10.3923
Wait this is easy just check all the angles then times them then you divide what you got and boom. You got you answer.
RT = sqrt(20^2 - 16^2)
RT = sqrt(400 - 256)
RT = sqrt(144)
RT = 12
SR/ST= QR/QT
SR/12 = 20/16
SR = 12 x 20 / 16
SR = 240/16
SR = 15
answer is C.
15 Units
