The length of x to the nearest tenth is; D: 38.6 m

<h3>Trigonometric ratios</h3>

The image of the triangle is missing and so i have attached it.

From the image attached, we can find the value of x by using trigonometry ratio.

We see that;

AB = x
AC = 10
∠BAC = 75°

Thus;

10/x = cos 75

10/x = 0.2588

x = 10/0.2588

x = 38.64 m

Approximating to the nearest tenth gives;

x = 38.6 m

What does evaluation of training measure?

mart [117]

Evaluation of training measure means the methodical process of gathering data and utilizing it to enhance your training .

What is training ?

Any action that aids in the knowledge or skill acquisition or improvement of current knowledge or skills is considered employee training and development. Talent development experts assist people in enhancing their performance at work through a formal training procedure. Development is the gain of knowledge, skills, or attitudes that equips individuals with new duties or directions. Employee development can take many different forms, with training being one particular and popular one. Other kinds include coaching, mentoring, informal learning, self-directed learning, or experiential learning.

Although the ADDIE model's evaluation step is the last, we should consider our evaluation strategy as early as the training design phase. Work with training designers and other key players to determine:

the goal of the evaluation, the evaluation questions, and the techniques used to get the data.

The target audience, organizational leaders, or other parties having an interest in the training may all be stakeholders in your training program.

1. Establish the goal of the evaluation.

An evaluation purpose describes the rationale for your evaluation. Consider who will utilize the findings, how they will be used, and what they need to know to help frame the evaluation's purpose.

We could use the results of training evaluations to:

creating a new training
Boost a current training
Give comments to the teacher
Check to see if the objectives of your training were met.

2. Devise the assessment queries.

In order to achieve your goals, create evaluation questions that fit. In contrast to specific test or survey questions that learners must respond to, assessment questions are general, overarching inquiries that support your evaluation objective.

Hence, evaluation of training measure means the methodical process of gathering data and utilizing it to enhance your training .

What would you do if you were born during World War Two

Nutka1998 [239]

It depends on what country I'm living in. If i lived in a place that Germany took over, I'd either go in hiding or flee. If i was in a place that Germany had no control over, I would do several things. I'd get as many jobs as I could and take any job that I could. I would do this because many things would be scarce during the war and therefore expensive. I would also do this to try and get home with a bomb shelter nearby with supplies. Then, I'd make sure I have a bag packed lightly with certain necessities in case I would have to quickly evacuate.

Follow the directions to convert the analog sound wave into a digital signal. the lines on the grid intersect at various points

dmitriy555 [2]

In this exercise we have to observe the axes of the graph to associate the values of X with those of Y that correspond to 0, 5, 5, -3, -5, -3, 2, 0, 0, -1, -2, 1, 1, -1, -1, -2, 2, 3, -1.

<h3>How to calculate the Cartesian plane?</h3>

Just draw two lines: one of them vertical, starting from the point until it finds the x axis; another horizontal, starting from the point until it meets the y-axis.

Then plotting the value of X on the graph we find the following for each value of X to Y:

X= 0 ; Y= 0;
X= 1 ; Y= 5;
X= 2 ; Y= 5;
X= 3 ; Y= -3;
X= 4 ; Y= -5;
X= 5 ; Y= -3;
X= 6 ; Y= 2;
X= 7 ; Y= 0;
X= 8 ; Y= 0;
X= 9 ; Y= -1;
X= 10 ; Y= -2;
X= 11 ; Y= 1;
X= 12 ; Y= 1;
X= 13 ; Y= -1;
X= 14 ; Y= -1;
X= 15 ; Y= -2;
X= 16 ; Y= 2;
X= 17 ; Y= 3;
X= 18 ; Y= -1;
