Answer:
m<4=40
Step-by-step explanation:
Supplementary angles form 180 degrees
m<3 is vertical to the 50 degree angle which is equal. 
so. m<3=50
m<5=90
90+50=140
180-140=40
m<4=40
 
        
             
        
        
        
Property of Addition and division.
 
        
             
        
        
        
35-4x>2
-4x>2-35
-4x>-33
-x>-33/4
x<33/4    (x<8.25)
Solution: x<8.25.  or  x∈(-∞ , 8.25)
        
             
        
        
        
B. 
sin^2x + cos^2x =1 
hence Sin^2x-1 = - cos^2x
