Respuesta :
cos 42° ~ 0.743
cos 42° = sin(90-42) = sin 58°
So sine of complementary angle also has same value as cos 42.
So sin 58 ~ 0.743
cos 42° = sin(90-42) = sin 58°
So sine of complementary angle also has same value as cos 42.
So sin 58 ~ 0.743
The sine of the complementary angle given that cos 42° = 0.743 is; sin 58° = 0.743
What is the Value of the Complementary angle?
We are given;
cos 42° = 0.743
Now, the sine of the complementary angle will have the same value as cos 42°.
Thus;
cos 42° = sin(90 - 42) = sin 58°
Thus, sine of the complementary angle is;
sin 58° = 0.743
