If the sin 90° = 1, then the cos 0° = (1 point)

cos 0° = 1

Step-by-step explanation:

In given triangle sin 90° = 1

and we know the relation between cosine and sin is represented by

sin x = cos (90-x)

Therefore, sin 90° = cos ( 90-90 )

                              = cos 0°

                              = 1

Therefore, cos 0° = 1 will be the answer.
