The pythagorean theorem, a^2+b^2=c^2, is used to calculate the side length of a right triangle. which equation can be used to calculate the missing side length, b, of a right triangle?

D b = sqrt(c^2 -a^2)

Step-by-step explanation:

We are using the Pythagorean theorem,

a^2+b^2=c^2

We want to solve for b

Subtract a^2 from each side

a^2 -a^2+b^2=c^2-a^2

b^2 = c^2 -a^2

Take the square root of each side

sqrt(b^2) = sqrt(c^2 -a^2)

b = sqrt(c^2 -a^2)

the answer is f(x)=2x-1

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
