If the measure of an angle is 360°, then the value of sin²θ + cos²θ = 1 will be 0² + 1² = 1. Then the correct option is B.
If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
|AC|² = |AB|² + |BC|²
where |AB| = length of line segment AB. (AB and BC are the rest of the two sides of that triangle ABC, AC being the hypotenuse).
The equation is given below.
sin²θ + cos²θ = 1
If the angle is 360°. Then the equation will be
sin²360° + cos²360° = 1
0² + 1² = 1
Then the correct equation is B.
