3.75

Step-by-step explanation:

$b = 5\\c=6.25\\a^{2} + b^{2} = c^{2} \\a^{2} +5^{2} = 6.25^{2} \\a^{2} + 25 = 39.0625\\a^{2} = 14.0625\\\sqrt{a^{2}} =\sqrt{14.0625} \\a = 3.75$

The missing side length is 3.75

x = 1.2; y = -2.8

Step-by-step explanation:

y = x -4

y = 6x -10

y -x = -4

y -6x = -10

Subtracting the equations:

5x = 6

x = 6/5 or 1.2

Substitute x = 1.2

y = 1.2 - 4

y = -2.8 or -14/5
