Answer:
We get value p=16
Step-by-step explanation:
When triangles are similar, the ratio of corresponding sides is equal.
In the given triangles we have to find value of p
We have the ratio: (Can use ratio of any two sides)
Now, putting values and finding p
So, we get value p=16

Answer:
(x, y) = (3, 12)
Step-by-step explanation:
Using the given variable definitions, we can write the equations ...
y = x + 9
2(x +y) = 30
__
Solving the second equation for y, we have ...
y = 15 -x
Substituting this into the first equation gives ...
15 -x = x +9
6 = 2x . . . . . . . . . add x-9
3 = x . . . . . . . . . . divide by 2
y = 3+9 = 12 . . . . substitute into the first equation
The numbers are (x, y) = (3, 12).
By the general application of cumulative property of addition :
x + y = y + x
