Use the inverse sine ratio when you know the length of a leg opposite the required angle. True or false

  False

Step-by-step explanation:

The function you use to find the angle will depend on the other information given. Regardless, finding the angle may involve the inverse sine function, not the inverse sine ratio.

If you know the leg adjacent as well as the leg opposite, the inverse tangent function will be an appropriate choice.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
