Answer:

a=9

Step-by-step explanation:

a^2+b^2=c^2

a^2+5.6^2=10.6^2

a^2+ 31.36=112.36

-31.36           -31.36

a^2=81

a=[tex]\sqrt{81}[/tex]

a=9

Answer:

9in

Step-by-step explanation:

is a right triangle so you can use Pythagorean Th.

(10.6)²= (5.6)² + a², subtract (5.6)² from both sides

(10.6)²- (5.6)² =  a²

81 =a², squareroot both sides

√81= √a²

±9 = a we only consider the positive solution because we use it for measurements so a=9
