Answer:

The reference angle will be {\theta}=45^{\circ}

Step-by-step explanation:

To solve for sin(-135), the reference angle can be obtained as follows:

= sin(-135)

=- sin(135) (Because sin(-{\theta})=-sin{\theta})

Thus, the above equation can be written as:

=-sin(180-135)

=-sin45

Hence , the reference angle will be {\theta}=45^{\circ}
