Percentage errors and percentage difference
Answer:
d = 41
Step-by-step explanation:
if the two lines are parallel, then 113 and 2x-5 are supplementary, which means that they add up to 180.
So:
113 + 2x - 5 = 180 =>
2x = 72
x = 36
Next step, we have three angles in the triangle that should add up to 180:
2x-5 + 2x + d = 180 with x=36
d = 180 - 139 = 41
so the angles are 72, 67 and 41
I believe the answer is D because domain is X and it is always (X,Y) so you take the X’s of the points and put them in order least to greatest and that will be your domain for this problem hope this helps
Answer:
Below
Step-by-step explanation:
Let's prove that cos^2(O) = 1+ cos(2O)/2
We khow that cos(2O) = 2 cos^2-1
● cos(2O) = 2 cos^2-1
Add one to both sides:
● cos(2O) +1 = 2 cos^2-1+1
● cos(2O) +1 = 2 cos ^2
Divide both sides by 2
● [cos(2O)+1]/2 = cos^2
