We cannot see which digit is underlines.
A point M on the unit circle could be represented by (x , y), which coordinates are nothing but cos Ф (for x) & sin Ф (for y, hence:
tan Ф = sin Ф / cos Ф ==> tan Ф (4/5) / (3/5) ==> tan Ф =(4/3).
Now let's calculate the angle: tan⁻¹Ф ==> tan⁻¹(4/3) ≈43°
Answer:
Step-by-step explanation:
They are adjacent angles.
Adjacent angles are right next to each, or side-by-side. Considered (by my math teacher) the next door neighbors.
Answer:
there is nothing there
