Answer:
   140°
Step-by-step explanation:
Angles 1 and 3 are "corresponding" angles, so are congruent.
   ∠1 = ∠3
   20x +60 = 30x +20
   40 = 10x . . . . . . . . . . . . subtract 20x+20
   4 = x . . . . . . . . . . . . . . divide by 10
   ∠1 = 20x +60 = 20(4) +60 = 80 +60
   ∠1 = 140°
 
        
                    
             
        
        
        
The way you wrote the problem makes the answer 330,600. I think your decimals were meant to be commas. If I am wrong, please forgive me.

So assuming that youmeans there were 35 MORE rose plants than sunflower seeds, then 
Rose:Sunflower =8:3
rose=sunflower+35
therefor
8 units=rose
3 units=sunflowers
rose-35=sunflower
8unit-35=3unit
5unit-35=0
5unit=35
therefor
35=5unit
divide by 5
7=1unit
so 8 units of roses
7 times 8=56
3 units of sunflowers
3 times 7=21
rose=56
sunflower=21
