h^2 = a^2 + b^2
8^2 = 6^2 + x^2
64 = 36 + x^2
x^2 = 64 - 36
X^2 = 28
x = square root(28) = 5.29150262

Using Pythagoras Theorem:
a^2 + b^2 = c^2
where a = ?
b = 6 cm
c = 8 cm
a^2 + 6^2 = 8^2
a^2 + 36 = 64
a^2 = 64 - 36
a^2 = 28
a = sq rt 28
a = 5.29 cm to 2 decimal places

8cm=c, 6cm=b, ?=a
c^2 - b^2 = a^2
64 - 36 = the square root of 28
so, "a" can equal the square root of 28cm; or "a" can equal 5.291502622cm; or about 5.3cm. Pythagorean theorem

c squared = a squared + b squared
a squared = c squared -b squared
a= square root of 8 squared - 6 squared
a= square root of 64-36
a= square root of 28
a= 5.292 cm

a^2 + b^2 = c^2
a = x
c = 8
b = 6
x^2 + 6^2 = 8^2
x^2 = 8^2 - 6^2
x^2 = 64 - 36
x^2 = 28
x = 5.29
