Answer:
x = 23
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
 =
 =  =
 =  = 3
 = 3
multiply both sides by (x - 10)
3(x - 10) = 39 ( divide both sides by 3 )
x - 10 = 13 ( add 10 to both sides )
x = 23

x= 5 
5+2y= 315
5-5+2y =315-5
2y = 310
2y/2 = 310/2
y=155
