Answer:
None of the answers are correct, because 12/15=4/5, it's equivalent to 12 divided by 15.
Step-by-step explanation:
Let Hypotenuse be x
X² = 20² + 28²
x² = 400 + 784
5.57142857143 there you go hopefully it's the answer you need
5/(3x+2) = 7/(5x-2)
<=>5*(5x-2) = 7*(3x+2) (x is not equal to -3/2 or 2/5)
<=> 25x -10 = 21x +14 (x is not equal to -3/2 or 2/5)
<=> 4x = 24 (x is not equal to -3/2 or 2/5)
<=> x = 6 (valid)
