If c=7.4 and a=3.6 then is my answer b^2=sqrt 41.8 or just b=sqrt 41.8

Step-by-step explanation:

a² + b² = c²

3.6² + b² = 7.4²

b² = 7.4² - 3.6² = 41.8

b = √41.8

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
