Answer:
56.25 cm
Step-by-step explanation:
your teacher wrote the approach already : the law of sines.
in our example we have
sin(28)/27 = sin(102)/c
c×sin(28)/27 = sin(102)
c×sin(28) = 27×sin(102)
c = 27×sin(102)/sin(28) = 27×0.98/0.47 = 56.25 cm
Overall, the total length of all the shelves is 2.2. I think that's what you mean?
For number 1. circle 4/5, 18/25, and 155/200
number 3 is. 7/12 so it is higher than one half!
number 4 is 10/20 so it is equal to 1/2
number 5 is 5/12 so it is smaller than 1/2
Step-by-step explanation:
x³ - 3x² + px ≡ x(x - 1)(x - q)
x³ - 3x² + px ≡ (x² - x)(x - q)
x³ - 3x² + px ≡ x³ + (-q - 1)x² + qx
By Comparing Coefficients, we have
Therefpre q = 3 - 1 = 2 and p = q = 2.
