Step-by-step explanation:
x+30°=4x(inscribed angle is equal to its arc)
4x-x=30°
3x=30°
x=30/3
x=10°
hope it helps.
Answer:
Step-by-step explanation:
Please refer to the attached image.
Recall that in order to find the equation of a line parallel to another one, one needs to have the actual slope of the original line. This is because one will need to give the same slope in the equation for the new line.
Let's now try to extract the slope of the first line by looking at its graph. Recall as well that the formula for the slope uses information from two points on the plane 
through which the line passes. We then try to find two points with easily identifiable coordinates. Please find two such points marked with red dots in the attached image. Their coordinates are also shown: (0,4) and (10,9).
Now let's use the formula for the slope (m) given two points
If we assign 
, and 
the slope becomes:
Then the parallel line we are going to build should also have slope "1/2"
Now, the next step is to create the equation of the new line using the slope m = 1/2 and also using the point (4,1) where it should be passing. So we use the "point-slope" formula to create the line:
where 
is the coordinate pair of thepont we want the line to go through (in our case the point (4,1)). Then:
which is the third option among your list of answers.
Answer: 1/3
Step-by-step explanation:
cotangent equals cos/sin. So the sin is 3. And cosecant is 1/sin. So that means its 1/3.
Answer: 9x+4
Step-by-step explanation: We take out the parentheses by multiplying both values by 2 (2 times x and 2 times 3) to get 2x-6. Now our equation is 9x+2x-6-2x+10. We can see that there is a +2x and a -2x so we just take both of them out as they cancel out each other. Now our equation is 9x -6+10. we add 10 to -6 to get +4. The result is 9x+4.
