Answer:
7.6
Step-by-step explanation:
a^2 + b^2 = c^2
6.5^2 + x^2 = 10^2
42.25 + x^2 = 100
isolate x by subtracting 42.25 on both sides
x^2 = 57.75
square root of 57.75 or 7.6
3 for the first one 2ed one is 5
(3x3) /9
first you triple the three (3x3) then divide by 9
any digit 0 to 9
Nothing about your description of the number suggests that the 10s digit depends on the units digit. The tens digit can be any digit 0 to 9.
