Step-by-step explanation:
Given

Required
Gaps: -2( )-2( )=8
<em>Fill in in the gaps</em>
The are numerous solutions to this.
One of them is:
Assume y = 0.
So, we have:



Divide through by -2


Fill in the gaps with these values of x and y respectively:
Hence; one solution is: 
90 degrees
Hope this helps
The angles should be included between the equal sides
