Answer:

$x=10$

$z=2$

$y=5$

Step-by-step explanation:

We know the triangles are congruent, therefore, each corresponding side of the triangle is also congruent!

1) Set EF≅CB

$x+15=2x+5$

$x+10=2x$

$x=10$

2) Set ED≅CA

$10z-5=3z+9$

$10z=3z+14$

$7z=14$

$z=2$

3) Set DF≅AB

$4y=8y-20$

$-4y=-20$

$y=5$

Step-by-step explanation:

6) x+y=60

x/y=7/5------(2)

x=(7/5)y

(7/5)y + y =60

(12/5)y=60

y=60(5/12)

y= 25

x=(7/5)y=(7/5)×25 =35

the two numbers are 35 and 25
