Answer: angle B= 54 degrees, a=6, b=8
Step-by-step explanation:
Add the two angles we have to get 126 degrees. Subtract that from 180 degrees to get 54 degrees.
We don't know enough to say which is which for a and b, but we can know that it is 6 and 8 because of pythagorean triples (3,4,5).
8t + 1 + (-4t) + (-6) =
8t + 1 - 4t - 6 =
4t - 5 <==
Since the degree of the
equation is 5, then the number of zeros is also equal to 5. We can find for the
1st value of the root by trial and error. To do this, we find for the value of
x which makes the equation equal to zero, that is:
<span>x^5 + 7x^4 + 2x^3 + 14x^2 +
x + 7 = 0 (find x)</span>
By trial and error I made
(which I will not show anymore), the possible root is -7. This is equivalent to
x + 7.
To find more roots, we
divide x^5 + 7x^4 + 2x^3 + 14x^2 + x + 7 by x + 7. The answer of the division results
in x^4 + 2x^2 + 1 which is a perfect square trinomial in the form of:
(x^2 + 1)^2
Therefore the other 4
roots are:
<span>x^2 + 1 = 0 ---> i, -i </span>
and
<span>x^2 + 1 = 0 ---> i, -i</span>
Therefore the answer is:
<span>1 real and 4 imaginary
zeros</span>
