Step-by-step explanation:
Two angles are Complementary when they add up to 90°.
Therefore
B : Nonlinear system of inequalities
Let's called the input 'z'
When we plug 'z' in the function we get ;
And we know that, this is equal to 19, so ;
Let's rearrange the equation.
So we have a quadratic equation here.
We'll use this formula to solve it :
The formula is used in equation formed like this :
In our equation,
a=2 , b=3 and c=-14
Let's plug in the values in the formula to solve,
So,
So the input can be both, 2 and
