Answer:
It's B for edge 2020
Step-by-step explanation:
That is a easy one the answer is 8
Answer:15
Explanation:Since these are similar triangles it means each contrasting side length has a ratio and the ratio for the side lengths is 1:3 based on 4:12 so you would multiple the side length of Db times 3 to find Ed and your answer is 15
Given that <span>∆ABC rotates around point D to create ∆A′B′C′.
</span>
<span>Line BC is a horizontal line such that the length of BC is 2 units. Also line AB is a vertical line such that the length of AB is 3 units.
Based on the position of B'C', shown in the figure, the coordinates of A′ are will be vertical to the cordinate of B' going downwards with a length of 3 units. This means that the x-value of the coordinate of A' is the same as that of B' but the y-value of the coordinate of A' is 3 units less than that of B'.
The coordinate of B' is (4, 4).
Therefore, the coordinate of A' is (4, 4 - 3) = (4, 1).</span>
