Step-by-step explanation:

apply pythagoras formula

Answer 2

Answer:

6 cm

Step-by-step explanation:

This can be solved by pythagoras theorem

In pythagoras theorem,

base squared + height squared= hypotenuse squared

so,

8*8 +x*x = 10*10

64 + x*x = 100

x*x= 100-64

x*x=36

x = square root of 36 = 6
