Answer:
53˚
Step-by-step explanation:
There are 360 total degrees in a 4-sided shape (You can find the total number of degrees in a polygon by using the formula 180(n – 2) where n is the number of sides).
so we can add up all the degrees and subtract them from 360.
67 + 135 + 105 = 307
360 - 307 = 53
