Question #31d49

Answer 1

155 degrees

Explanation:

The sum of the interior angles of any polygon with n sides is given by the formula:
`S=(n-2)*180`

When we plug in 4 for the number of sides we get that the value is 360.

Now we just subtract the other angles from 360 to get to the missing angle:

`360-100-45-60=155`
