Solve for A: R=AS/(A+s)

Define coprime numbers

Two numbers are coprime if their only common divisor is 1

C = {(1/2, 5), (-3, 7), (3/2, 5), (1/2, -1)} What are the domain and range of each relation? Is the relation a function?

domC={1/2, -3, 3/2}
ranC={5, 7, -1} 
not a function, 1/2 is mapped to two different numbers

In a 30-60-90 triangle ABC with hypotenuse lineAC=6, find the lengths of the other two sides

AB=3

AC=6

In a 45-45-90 triangle ABC with right angle B, and leg line AB=8, find the length of the hypotenuse.

in a 45-45-90 triangleABC with hypotenuse lineAC=7, find the lengths of the legs.

In a 30-60-90 triangleABC with right angleB, and shortest leg lineAB=5, find the lengths of the other two sides" please and thank you.

AB=5
BC=10
