Triangle ABC is graphed on the coordinate plane below. What is the approximate length of segment AB in units.​

5 units

Step-by-step explanation:

Count from point A to point B on the x-axis.

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

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
