Mathematics
1 answer:

8 0

Answer:

x = 20

Step-by-step explanation:

Since ΔACB ≅ ΔDCE then ∠A ≅ ∠D, that is

3x - 10 = 2x + 10 ( subtract 2x from both sides )

x - 10 = 10 ( add 10 to both sides )

x = 20

How is the answer 35? How do I get it?
vlabodo [156]
I think it's -35. The steps to get that number is subtracting the 3 to the right side. Then you have -2 - 3 which equals to -5. Then you still have x/7= -5. Get rid of 7 from the x and do the same thing to the other side but you multiply 7 and -5. Last you your would be x= -35.
