Answer:
18 degrees
Step-by-step explanation:
The triangle is an iscoceles right triangle. 
The angles in a triangle add up to 180. 
90+2y (iscoceles) =180
2y=90
y=45
So the angles of the right triangle are 45. However, you have to take away 27 because you are solving for only a part of 45. 45-27=18
 
        
                    
             
        
        
        
5 1/6 * (-2/5) = __
turn 5 1/6 into a mixed fraction
31/6 * (-2/5) = __
multiply
31 * -2 = -62
6 * 5 = 30
so -62/30 or -2 1/15
