Since 2x = x+5, we have x = 5.
 
        
             
        
        
        
Answer:
A = bh/2
39 = b*3/2
39*2 = b*3/2 * 2
78 = b*3
78/3 = b*3/3
26 = b.
Alors, la grande base est 26 cm et le petit base serait 26/3 = 8.67 cm arrondi. 
 
        
             
        
        
        
The 3 inside angles of a triangle need to equal 180 degrees. Looking at the larger outside triangle the top angle is 30 and the lower right angle is 60.
30 + 60 = 90
The lower left angle needs to be 180 - 90 = 90 degrees.
That angle is split into two angles with one given as 70.
This means X needs to be 90 - 70 = 20 degrees.
x = 20
