Answer:
Step-by-step explanation:
Sin(x)=40/50
x= sin^-1(40/50)
x= 53.1301023542—>53.1 rounded to the nearest tenth
angle of elevation is 53.1
Answer: The slope is 5
Step-by-step explanation:
You can calculate the slope of the line with this fomula:

Given the points (2,3) and (1,-2), you can identify that:

Now, the final step is to substitute these values into the formula
, getting that the slope of this line is:


Keep subtracting 6 until you hit the 20th term. Hope this helps
