Answer:
1/4÷2=1/8 ur welcome use photomath trust me
The answer would be 20
A squares sides are equal and there are 4 of them so you take 80 (the total perimeter) and divide that number by 4 (number of sides) and you get 20
The angle that is same side exterior angle to ∠ABC is ∠EFH.
<h3>How to find angles?</h3>
When parallel line are cut by a transversal line, angle relationships are formed such as corresponding angles, vertically opposite angles, alternate angles, same interior angles, etc.
AD and EG are parallel to each other.
CH is a transversal line to the parallel lines.
Therefore, let's find the angle that has the same relationship as same side exterior angles as angle ABC.
Two angles that are exterior to the parallel lines and on the same side of the transversal line are called same-side exterior angles.
Same side exterior angles are supplementary.
Therefore,
∠ABC and ∠EFH are same side exterior angles.
