Given:
The figure of a right angle triangle.
To find:
The measure of side AB.
Solution:
In a right angle triangle,
[tex]\cos \theta=\dfrac{Adjacent}{Hypotenuse}[/tex]
In the given triangle,
[tex]\cos B=\dfrac{BC}{AB}[/tex]
[tex]\cos (20^\circ)=\dfrac{7}{AB}[/tex]
[tex]\cos (20^\circ)AB=7[/tex]
[tex]AB=\dfrac{7}{\cos (20^\circ)}[/tex]
On further simplification, we get
[tex]AB=\dfrac{7}{0.93969}[/tex]
[tex]AB=7.449265[/tex]
[tex]AB\approx 7.45[/tex]
Therefore, the measure of AB is 7.45 units.

The owner of a garden center pays $25 for each birdbath . She sells them for 15% more than she paid. Decide whether each expression represents the selling price for b birdbaths.
Answers
Answer:
The selling price is $28.75b.
Step-by-step explanation:
There are no options given but I will represent the word problem mathematically.
Let b stand for all the birdbath. If the owner pays $25 for each, then he pays $25b.
Selling them for 15% more means, 15% of the cost price was added to the original price. Finding 15% of cost price we have:
15% x $25b = 0.15 x $25b = $3.75b.
Therefore, the selling price is given as
$25b + $3.75b = $28.75b.

Amos scored 100 points while playing 3 rounds of a game.
Points
Round 1 - 30
Round 2 - 25
Round 3 - ?
Total - 100
How many points did he score in round 3?
Complete the steps to solve the problem.
1. What do you need to solve for this problem? Choose a variable to represent this unknown value.
2. Using the variable you chose, write an equation to represent this situation. (Hint: You may want to put the number of points in each round on one side and the total number of points on the other.)
3. Solve this equation to find how many points Amos scored in round 3. Show your work.
Answers
1. We can subtract the scores of the first and second rounds from the total score to obtain the score in the third round.
2. An equation including a variable to solve would be x + 30 + 25 = 100.
3. By solving the equation we obtain Amos scored 45 points in the third game.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
From the given information the score for her third round would be,
= (100 - 30 - 25).
= 100 - 55.
= 45.
Another way to solve this problem is assuming Amos scored 'x' in the third game.
Therefore, (30 + 25 + x) = 100.
55 + x = 100.
x = 100 - 55.
x = 45.
