Answer:
20.5 degrees
Step-by-step explanation:
So when the arc is being made from two lines coming out from the center, the measure of the arc is the same as the angle of the lines.
So the measurement of 41 degrees for the arc is also the angle of line OB and line OC.
Now that center line is the diameter, which means it is 180 degrees
So you can find the angle of line OA and OB:
180 - 41 = 139
Then, to find x you need to recognize that OB and OA is actually the radius of the circle, which means they are the same length.
This makes it an isosceles triangle. So, the angle of OB and BA is the same as OB and BA. The measurement of all the angles in a truianbgle is 180 degrees, so to find the measurement of x, you need to subtract 139 from 180:
180-139 = 41
And then divide by two to find the remaining two angles:
41/2 = 20.5
and that is x :)
Answer:
n = -4
Step-by-step explanation:
Start off by remembering PEMDAS which first P means parenthesis so use distributive property to multiply the 2n + 4 by the 3 in front of it and do the same to the n + 1 and multiply that by the 5 in front which turns your question into 6n+12-2=1+5n+5 so now i'd combine like terms on both sides which now gives you 6n + 10 = 5n +6 so now to get the n on one side i'm going to sub tact it from both sides doesnt matter which one you do but to make it easier i'd subtract the 5n from the 6n because the whole point is to solve for n and by doing that you'd already be getting it by itself. so now the question should look like n + 10 = 6 so subtract 10 from both sides to isolate the n and you get your answer n = -4
