Answer:

Step-by-step explanation:

2a + 2/a = 4

a + 1/a = 2

a^2 + 1 = 2a

a^2 - 2a +1 = 0

(a-1)^2 = 0

a = 1

2(1)^2 + (2/(1)^2) = 4

FinnZ [79.3K]
C^2=a^2+b^2  we are given the hypotenuse of 19 units and one leg of 8 units so:

19^2=8^2+b^2

361=64+b^2

b^2=297

b=√297

b≈17.2 to the nearest tenth
