Answer:
If sin 115 degrees≈ 0.91 and cos 115 degrees = -0.42, then sin -115 = -0.91 and cos -115 degrees = 0.42
Step-by-step explanation:
Answer:
Step-by-step explanation:
2x=5x+60.
0=3x+60 ( subtract 2x from both sides)
-60=3x(subtract 60 on both sides)
x=-20
Hope this helps plz mark brainliest if correct :D
Answer:
A- control group
Since group A is tested under normal condition, it is the control group. Control group is separated from other groups so that the independent variable being tested cannot influence the result.
Answer: Choice C) Same-side interior angles
------------------------------------------------------------------------------
Angle 4 and angle 6 are on the same side, in this case the right hand side of the transversal line (line t). In addition, they are on the interior of the "train tracks" horizontal lines (line a and line b). Combine this and this is why the two angles are same-side interior angles
Side note: if line a is parallel to line b, then angle 4 and angle 6 add to 180 degrees. At this point, they are considered supplementary.
