Given a polynomial p(x) with leading coefficient and solutions
, we have
That's why we have to find the solutions first. We complete the square by adding 3 to both sides:
From here, we continue by taking the square root of both sides:
So, the two solutions are
Which yields the factorization
Answer:
The ratio for sin(X) is
The ratio for cos(X) is
Step-by-step explanation:
- The ratio of the sine of a right triangle is:
Since we need the ratio for angle X, . From the picture we can infer that the opposite side of X is
. The hypotenuse (the side opposite to the right angle) is 12, so replacing the values:
- The ratio of the cosine is:
Similarly, , adjacent side = 5, and hypotenuse = 12, so
