Answer:
a =5.3
Step-by-step explanation:
The Pythagorean theorem is
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + 6^2 = 8^2
a^2 +36 = 64
Subtract 36 from each side
a^2 +36-36 = 64-36
a^2 =28
Take the square root of each side
sqrt(a^2) = sqrt(28)
a = 5.291502622
To the nearest tenth
a =5.3
