Answer:
   40°
Step-by-step explanation:
Triangles QRS and QTS are congruent (HL), so the marked angles are also congruent:
   3x +2 = 4x -4
   6 = x
Then the total angle measure of angle RST is ...
   (3x +2) +(4x -4) = 7x -2 = 7(6) -2 = 40 . . . degrees
m∠RST = 40°
 
        
             
        
        
        
1-8 is simple. Just subtract 8 from 1. so 1-8 = -7
