Answer:
The value of BEF = 36°
Step-by-step explanation:
Given:
Angle AED = 90°
Angle BEF = 3x°
Angle CEF = 54°
Find;
The value of BEF
Computation:
We know that;
Angle AED = Angle BEC (Vertical opposite angle)
So,
Angle AED = Angle Angle BEF + Angle CEF
90 = 3x + 54
3x = 90 - 54
3x = 36
x = 36 / 3
x = 12
The value of BEF = 3x 
The value of BEF = 3(12)
The value of BEF = 36°
 
        
             
        
        
        
18 / 2 = 9 || 9 x 3 = 27. Therefore, 27 students are registered in Bob’s class.
        
             
        
        
        
180-134=46 98+46=144. 180-144=36. angle y=36. So the answer is D)36.
