Solution here,

In the figure, the upper small triangle is similar to a lagre triangle.

Now, from the property of similar triangle,

$\frac{5}{40 + 5} = \frac{3}{3 + 2x + 10} \\ or \: \frac{5}{45} = \frac{3}{13 + 2x} \\ or \: 13 + 2x = 27 \\ or \: 2x = 27-13 \\ or \: x = \frac{14}{2} \\ or \: x = 7$

therefore, x= 7

The numbers are x and y
x>y

x=5+2y

sub 5+2y for x
5+2y-y=13
5+y=13
y=8

sub back
x-y=13
x-8=13
21=x

the numbres are 21 and 8
