Step-by-step explanation:
In a right triangle, the cosine is the ratio of the adjacent side to the hypotenuse:
The adjacent side is the side that makes up the angle but is not the hypotenuse.
I'm assuming the answer box should ask for cos(theta) rather than cos(x).
The value of 'k' in the quadratic Equation having one rational solution is k is 8.
- Quadratic equations are the polynomial equations of degree 2 in one variable of the type
where a, b, c, ∈ R and a ≠ 0.
- The standard form of a quadratic equation is
.
Here, the given equation is
By comparing the given equation with the standard form of the quadratic equation we get,
a = 4
b = k
c = 4
The given quadratic is having one rational solution, which means
Therefore,
Therefore, the value of k is 8.
