In ΔABC, m∠B = 90°, cos(C) = , and AB = 16 units. Based on this information, m∠A =(62,33,28) °, m∠C =(62,33,28) °, and AC = (22,34,10) units. Note that the angle measures are rounded to the nearest degree.

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

y-3=-3/2(x+4)

ur very much welcome

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.
