Step-by-step explanation:

already explained.

Answer 2

Answer: x = 5

Step-by-step explanation:
I am not very good at explaining but
Side x corresponds to side 11
And side 4 corresponds to side 10

The triangle got bigger

Side 4 increased by 6 to get 10
So you increase c by 6 to get 11
x + 6 = 11
x = 11 - 6
x = 5
