Answer:
See below.
Step-by-step explanation:
The lines on the sides of the figure represent congruency. We'll solve x first by taking the lines with the values x + 6 and 2x + 4. Since they are congruent, they are equal.
2x + 4 = x + 6
x + 4 = 6
x = 2
Now that we know that x is equal to 2, we can solve for the two congruent lines at the top.
y - 4 = x + 5
y - 4 = (2) + 5
y - 4 = 7
y = 11
Now you can substitute those values to find the side lengths.
y - 4 = 11 - 4 = 7
x + 5 = 2 + 5 = 7
2x + 4 = 2(2) + 4 = 4 + 4 = 8
x + 6 = 2 + 6 = 8
