trying to find the missing angle of 45degrees and 160 degrees?

What kind of figure?

left triangle

There are only 180 degrees in a triangle. What were those angles again?

To find the missing angle between 45 degrees and 160 degrees, you need to subtract the known angle from 180 degrees. Since the sum of all angles in a triangle is 180 degrees, the missing angle can be determined as follows:

Missing angle = 180 degrees - (known angle)

In this case, the missing angle can be calculated as:

Missing angle = 180 degrees - 45 degrees
Missing angle = 135 degrees

Therefore, the missing angle between 45 degrees and 160 degrees is 135 degrees.
