Step-by-step explanation:
The triangles are similar by AA, so because corresponding sides of similar triangles are proportional,
(x+15)/15 = 12/10
(x+15) = 18
x = 3
Answer:
Step-by-step explanation:
Multiply the first by -2
Multiply the second by 3
so the x variable can be cancelled,eliminated
3x +2y =17
2x+5y = 26
-6x - 4y = -34
6x +15y = 78
11y = 44
y=4
Now plug this value to get x
3x+8 = 17
3x = 9
x=3
The answer (3,4)
