The concept of similar triangles will be applied.

It is evident that the AAA congruence property is responsible for the similarity of the two triangles in the 2 cases. The theorem is

- Triangles are similar if the measure of all three interior angles in one triangle are the same as the corresponding angles in the other.

So, the corresponding sides from the two triangles can be written as a ratio of one another

17)

The most obvious tell here is the largest angle in the two triangles, the sides directly opposite this angle in the two triangles can be written in a ratio such that

(95.2/13.6) = 7

indicating that the bigger triangle is exactly 7 times the smaller one.

So,

(95.2/13.6) = (53.2/7.6) = (x/8.3) = 7

x = 7 × 8.3 = 58.1

18)

The obvious tell here is the smallest common angle for the two triangles, the two other corresponding sides can then be written in a ratio, matching the bigger side in the two triangles to each other.

(39.5/7.9) = (37.5/7.5) = (x/3.4)

(x/3.4) = 5 (Indicating thay the bigger triangle is 5 times bigger than the smaller one.

x = 3.4 × 5 = 17 units.

Hope this Helps!!!

Name and describe the methods for determining a marketing budget.

Mekhanik [1.2K]

Answer: There are several ways in which we can determine our marketing budget. Some of these are given below:

1. Percentage of revenues:

Under this method we usually take a fixed percentage of our revenues and further allocating this amount for marketing. We will choose the percentage that works best for us.

2. Percentage of net sales:

This method determines our marketing budget as a fraction of our net sales. This method will take a lot of trial and error to find the percentage that works well for our company.

3. Industry specific:

Nowadays, industries have specific projections as to the amount they will need to spend on marketing . The best way to get these numbers is to find a firm that represents our industry and ask them to provide us with averages. We can then refine the actual costs.

4. Objective/task oriented 

This is model that works by setting out goals, planning out the tasks and then estimating the cost for all of these tasks. It works greatly for firms who have a immense knowledge about measurements and information of their business processes.

Solve each inequality. The variable should be on the left-hand side in your solution.

lara [203]

Answer:

x≤ −96 /23

Step 1: Simplify both sides of the inequality.

Step 2: Subtract 1/8x from both sides.

Step 3: Subtract 12 from both sides.

Step 4: Multiply both sides by 8/23.
