The area of the entire sector is
The area of the triangle OAB is .
So, the area of the segment is
sin 40° = 0.6428
<u>Step-by-step explanation:</u>
The complementary ratio of sine is cos and vice-versa.
sin θ = cos (90 - θ)
cos θ = sin (90 - θ)
So cos 50° = sin (90 - 50)°
= sin 40°
sin 40° = 0.6428
This indicates that the complement of cos 50° is sin 40° which is equal to 0.6428.
