The sum of the measures of two supplementary angles is 180 degrees.

The second angle measures x.
The first angle measures 20 deg more than x, or x + 20.

The sum of their measures is 180 deg.

x + x + 20 = 180

2x + 20 = 180

2x = 160

x = 80

The second angle measures 80 deg.

x + 20 = 80 + 20 = 100

The first angle measures 100 deg.

Answer: The first angle measures 100 deg, and the second angle measures 80 deg.

If f(x) = x² – 5, evaluate: f(x+h)-f(x)/<br> h
Likurg_2 [28]

The first derivative of the function f(x) = x² - 5 is equal to f'(x) = 2 · x.

<h3>How to find the derivative of a quadratic equation by definition of derivative</h3>

In this question we have a quadratic function, in which we must make use of the definition of derivative to find the expression of its first derivative. Then, the procedure is shown below:

f(x) = x² - 5                                         Given

f' = [(x + h)² - 5 - x² + 5] / h                Definition of derivative

(x² + 2 · x · h + h² - 5 - x² + 5) / h       Perfect square trinomial

(2 · x · h + h²) / h                                Associative, commutative and modulative properties / Existence of additive inverse

2 · x + h                                              Distributive, commutative and associative properties / Definition of division / Existence of multiplicative inverse

2 · x                                                     h = 0 / Result

The first derivative of the function f(x) = x² - 5 is equal to f'(x) = 2 · x.
