Answer:
both each side of each triangle is equal
use alphabets to mark each edge of the triangles and prove congruency
Okay, let's add the two x values.
10x + 75 = 5x = 110
15x + 75 = 110
Now let's minus 75 from each side.
15x = 35
Now let's divide each side by 15.
x = 2.333333333
Then the answer is 17 minus 8 times the square root of 2, or 5.68629
11.25/375 = 0.03 which is 3%
