With the given data, the first step to take is to use MS excel to plot the data then determine the trendline in which the equation's r2 value is closest to 1. From the plot obtained from Excel, the plot is a second degree polynomial and not an exponential function. the answer hence is no.
By using <em>algebra</em> properties and <em>trigonometric</em> formulas we find that the <em>trigonometric</em> expression
is equivalent to the <em>trigonometric</em> expression
.
<h3>How to prove a trigonometric equivalence by algebraic and trigonometric procedures</h3>
In this question we have <em>trigonometric</em> expression whose equivalence to another expression has to be proved by using <em>algebra</em> properties and <em>trigonometric</em> formulas, including the <em>fundamental trigonometric</em> formula, that is, cos² x + sin² x = 1. Now we present in detail all steps to prove the equivalence:
Given.
Subtraction between fractions with different denominator / (- 1) · a = - a.
Definitions of addition and subtraction / Fundamental trigonometric formula (cos² x + sin² x = 1)
Definition of tangent / Result
By using <em>algebra</em> properties and <em>trigonometric</em> formulas we conclude that the <em>trigonometric</em> expression
is equal to the <em>trigonometric</em> expression
. Hence, the former expression is equivalent to the latter one.

Step-by-step explanation:
Given:
Complementary angle = 68'
Angle measure = 90' - 68' = 22'
Supplementary angle = 180' - 22' = 158'
Angle classification = Acute angle
Given:
Supplementary angle = 161'
Angle measure = 180' - 161' = 19'
Complementary angle = 90' - 19' = 71'
Angle classification = Acute angle
Given:
Angle measure = 136'
Angle classification = Obtuse angle
Complementary angle = 136' - 90' = 46'
Supplementary angle = 180' - 136' = 44'
