Answer:
Since the kite is flying, the hypotenuse side of the triangle is 32.4m, while the adjacent side is unknown.
Given the opposite and hypotenuse, we use sine to find the angle.
θ= 34.4° (1 d.p.)
Thus, the angle the kite string makes with the ground is 34.4°.

Step-by-step explanation:
1. Quadratic function : in which maximum power of is two.
The roots of quadratic function can be either equal or different.
For example:
will have two equal roots i.e. 1 and 1.
will have two different roots i.e. 1 and 2.
So, <em>sometimes </em>is the correct answer.
2. Cubic function has atleast 1 real root.
Cubic function has maximum power of as 3.
If the coefficients are real numbers then atleast 1 real root.
If the coefficients are imaginary in nature, then this is not true.
For example:
Cubic equation does not have any real root.
Cubic equation has a real root x = -1.
So, it is sometimes true.
3. A function with degree 5 i.e. maximum power of as 5 will have 5 roots.
It is always true that a function will have number of roots equal to its degree.
4. Quadratic function can have only 1 complex solution.
Two complex solutions are also possible for a quadratic function.
For example:
will have two imaginary roots:
It is also possible to have 1 complex solution,
For example:
will have one complex root and one real root.
So, the statement is <em>sometimes </em>true.
