Answer:
4.
Step-by-step explanation:
(sec α - tan α)(sec α + tan α) = sec^2 α - tan^2α 
But sec^2  α = 1 + tan^2 α so 
sec^2 α - tan^2α  = 1 + tan^2 α - tan^2α
= 1
so 1 =  (sec α - tan α)(sec α + tan α) = 1/4 * x     where x  is sec α + tan α
 1/4 * x = 1
x = 4.
 
        
             
        
        
        
Supplementary means they equal 180 when added. Therefore:
X+56+3x=180
Combine common units
4x+56=180
Subtract 56 from both sides
4x=124
Divide by 4
X=31
Now we know the smaller angle is 31 degrees. Now we plug that into the larger angle:
3(31)+56
93+56
149
The larger angle is 149 degrees. 
I hope this Helps!
