Answers:
cos(A) = 0.8480
tan(B) = 1.6
=============================================
Explanation:
Before we can compute cos(A), we'll need to find the hypotenuse.
Use the pythagorean theorem.
a^2 + b^2 = c^2
8^2 + 5^2 = c^2
89 = c^2
c^2 = 89
c = sqrt(89)
The hypotenuse is exactly sqrt(89) units long.
This will allow us to find the cos(A) value
cos(angle) = adjacent/hypotenuse
cos(A) = AC/AB
cos(A) = 8/sqrt(89)
cos(A) = 0.84799830400509 which is approximate
cos(A) = 0.8480 when rounding to four decimal places
-------------------------
For the tangent ratio, we won't use the hypotenuse. Instead, we use the opposite and adjacent sides like so:
tan(angle) = opposite/adjacent
tan(B) = AC/BC
tan(B) = 8/5
tan(B) = 1.6

Based on the definition of supplementary angles and linear pair, a counterexample to the statement is: option B.
<h3>What are Supplementary Angles?</h3>
If two angles add up to give 180 degrees, they are regarded as supplementary angles.
<h3>What is a Linear Pair?</h3>
A linear pair is two adjacent angles that share a common side on a straight line, and have a sum of 180 degrees. Linear pair angles are supplementary angles.
In the image given, figure D is a perfect example of a linear pair that are supplementary.
However, in figure B, we have two angles that are not adjacent angles on a straight line but are supplementary angles.
Therefore, a counterexample to the statement is: option B.

Answer:
D
Step-by-step explanation:
If Jeremy has saved $89 already, he still needs more money.
Finding the difference between 130 and 89 will give you 41.
$89- what Jeremy saved already
$41- what Jeremy needs to save
$130- the total price of the bird bath
x- $41 dollars
