Using Cos formula of a triangle
let BA be x
x² = a² + b² -2abCos(90°)
x² = 64 + 196
x = √260
To find <B using Cos again
b² = a² + c² - 2acCos(B)
196 = 64 + 260 - 2 * 8 * √260 * cosB
196=324 - 16√260 *cosB
324-196=16√260CosB
8 = √260CosB
CosB = 8/√260
B = cos-¹(8/(√260))

4 markers cost $7.04. (The photo didn’t load up the first time when I asked the question. It’s a writing proportion question)
9514 1404 393
Answer:
4/7 = $7.04/x
Step-by-step explanation:
You can write the proportion 4 different ways. Any way you write it, you want markers in corresponding positions and prices in corresponding positions.
Here the best choice is ...
(reference quantity)/(different quantity) = (reference price)/(different price)
4/7 = $7.04/x
__
Additional comment
Many people might choose to put the unknown in the numerator:
x/$7.04 = 7/4
or
x/7 = $7.04/4
Answer: None of the above
Step-by-step explanation:
The easiest way to get the cost is to get the cost per unit times the number needed.
x = 7($7.04/4 ) To make that into a proportion it would look like
x/7 = $7.04/4
[tex]\frac{x}{7} =\frac{7.04}{4}[/tex]

A bike shop charges a fee for renting a bike, depending upon how long it is used. Riders who bring their own helmet are instead charged a discounted fee.The graph shows how the fees are related.
ASAP DUE RIGHT NOW !!!!
Answer:
Each discounted fee is $5 less than the rental fee.
Step-by-step explanation:
Each discounted fee is $5 less than the corresponding rental fee, and the percentage discount decreases as the rental fee increases.
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
We can determine the discounted fee for each rental fee by looking at the coordinates on the graph.
The x-axis represents the rental fee, and the y-axis represents the discounted fee.
For example, at a rental fee of 10, the discounted fee is 5, so we have the point (10, 5) on the graph.
To calculate how much each discounted fee is less than the rental fee, we can subtract the discounted fee from the rental fee.
For example, at a rental fee of 10 and a discounted fee of 5, the discounted fee is $5 less than the rental fee of $10.
This means that the discounted fee is 50% less than the rental fee.
Using this method for each point on the graph, we get:
At a rental fee of 10, the discounted fee is 5, which is $5 less than the rental fee.
Therefore, the discounted fee is 50% less than the rental fee.
At a rental fee of 20, the discounted fee is 15, which is $5 less than the rental fee.
Therefore, the discounted fee is 25% less than the rental fee.
At a rental fee of 30, the discounted fee is 25, which is $5 less than the rental fee. Therefore, the discounted fee is 16.67% less than the rental fee.
At a rental fee of 40, the discounted fee is 35, which is $5 less than the rental fee. Therefore, the discounted fee is 12.5% less than the rental fee.
Thus,
Each discounted fee is $5 less than the corresponding rental fee, and the percentage discount decreases as the rental fee increases.
