Answer:

Step-by-step explanation:
In order to find the value of ∠EFB here, we have to note our angle relationships. 
We know that ∠CFE is already 90°. We also know that ∠CFA is 90°. Angle ∠AFB is inside ∠CFA. Since we know the measure of ∠AFB, we can find the measure of ∠BFC.

Now that we know ∠CFE and ∠BFC, which together make ∠BFE, we can add these angles up.

Hope this helped!
 
        
             
        
        
        
22 need more
150-56=94
20*3 = 60
94-60 = 34
34-12= 22
