Triangle abc and triangle cde are similar right triangles. which proportion can be used to show that the slope of ac is equal to the slope of ce? a) 0 − 2 / 3 − 0 = 2 − 4 / 6 − 3 b) 2 − 0 / 3 − 0 = 4 − 2 / 6 − 3 c) 2 − 0 / 3 − 0 = 4 − 2 / 3 − 6 d) 2 − 0 / 0 − 3 = 4 − 2 / 6 − 3

B)

Step-by-step explanation:

1. You can calculate the slope by applying the following formula:

2. The point A is (0,0) and the point C is (3,2).

Where:

3. The point C is (3,2) and the point E is (6,4).

Where:

4. Then, you have:

5. Therefore, the slope of AC is equal of the slope CE.

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
