Answer:
X= 7
Y= 16
Step-by-step explanation:
Solve x then Y
In every right triangle, if you add up the squares of the two
shorter sides, you get the square of the longest side. If you
don't then it's not a right triangle.
10² = 100
24² = 576
100 + 576 = 676
676 is the square of 26.
It's NOT the square of 28.
So 10 - 24 - 28 is not a right triangle.
