Trapezoid A B C D is shown. Diagonals are drawn from point B to point D and from point A to point C and intersect at point E. If quadrilateral ABCD is an isosceles trapezoid, which statements must be true? Select three options

BC ∥ AD
BD ⊥ AC
BA ≅ CD
BE ≅ ED
∠CBA ≅ ∠BCD

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

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4
