Find the missing Angle
These are the four steps we need to follow:Step 1 Find which two sides we know – out of Opposite, Adjacent and Hypotenuse.Step 2 Use SOHCAHTOA to decide which one of Sine, Cosine or Tangent to use in this question.Step 3 For Sine calculate Opposite/Hypotenuse, for Cosine calculate Adjacent/Hypotenuse or for Tangent calculate Opposite/Adjacent.Step 4 Find the angle from your calculator, using one of sin-1, cos-1 or tan-1ExampleFind the size of angle a0Step 1 The two sides we know are Adjacent (6,750) and Hypotenuse (8,100).Step 2 SOHCAHTOA tells us we must use Cosine.Step 3 Calculate Adjacent / Hypotenuse = 6,750/8,100 = 0.8333Step 4 Find the angle from your calculator using cos-1 of 0.8333:cos a0 = 6,750/8,100 = 0.8333cos-1 of 0.8333 = 33.60 (to 1 decimal place)Example #1Find the missing angle when you are given the following dimensions.BC = 3; AC = 16; AB = 8, Cos ? = 3/16ExplanationThe missing value is x than Cos 3 / 16Cos x = 0.2x = Cos-1 0.2x = 78.5Answer = 78.50Practice Problem #1:Find the missing angle:BC = 10 ; AC = 18 ; AB = 7, Sin__?__ = 7 / 18Explanation #1The missing value is x than Sin 7 / 18Sin x = 0.4x = Sin-1 0.4x = 23.60Answer = 23.60Practice Problem #2)Find the missing angle:BC = 24 ; AC = 13 ; AB = 4, tan_?___ = 13 / 24Explanation #2The missing value is x than tan 13 / 24tan x = 0.5x = tan-1 0.5x = 26.60Answer = 26.60Practice Problem #3)Find the missing angle:BC = 18 ; AC = 33 ; AB = 15, Cos__?__ = 18 / 33Explanation #3The missing value is x than Cos 18 / 33Cos x = 0.5x = Cos-1 0.5x = 600Answer = 600ReviewDirections: Find the missing angle in each of the following problems.1.

Walden University Testing for Correlation and Bivariate Regression Paper
Assignment: Testing for Correlation and Bivariate Regression You had the chance earlier in the week to perform an article critique on correlation and simple linear regression and obtain peer feedback. Hopefully you are excited about the potential these tests hold; equally important is that you recognize some of their weaknesses. Now, it is once again time to put all of that good brainstorming to use and answer a social research question with the correlation and simple linear regression. As you begin the Assignment, be sure and pay close attention to the assumptions of the test. Specifically, make sure that your variables are metric level variables that can easily be interpreted in these tests. For this Assignment, you will examine correlation and bivariate regression testing. To prepare for this Assignment: Review this week’s Learning Resources and media program related to regression and correlation.Using the SPSS software, open the Afrobarometer dataset or the High School Longitudinal Study dataset (whichever you choose) found in the Learning Resources for this week.Based on the dataset you chose, construct a research question that can be answered with a Pearson correlation and bivariate regression.Once you perform your correlation and bivariate regression analysis, review Chapter 11 of the Wagner text to understand how to copy and paste your output into your Word document. For this Assignment: Write a 2- to 3-paragraph analysis of your correlation and bivariate regression results for each research question. Do not forget to evaluate if the correlation and bivariate regression assumptions are met and report the effect size. In your analysis, display the data for the output. Based on your results, provide an explanation of what the implications of social change might be.Refernces Laureate Education (Producer). (2016b). Correlation and bivariate regression [Video file].
