Answer: C is the correct statement " In ΔADC and ΔBCD AD=BC, opposite sides of a rectangle are congruent"which completes the proof .
Step-by-step explanation:
Given: A figure shows a rectangle ABCD having diagonals AC and DB.
Anastasia wrote the proof given in picture to show that diagonals of rectangle ABCD are congruent.
We can see the Statement 2 which tells that AB=CD, opposite sides of a rectangle are congruent. In Statement 3 she used Pythagoras theorem to show AC²= BD² by using Statement 1 and 2.
Thus we can see she need to introduce two triangles named as ACD and BCD and the remaining sides to write the proof is AD=BC with correct reason i.e. opposite sides of a rectangle are congruent.
Therefore Statement 1 would be In ΔADC and ΔBCD AD=BC, opposite sides of a rectangle are congruent.
Answer:
8x= y
Step-by-step explanation:
from what a can see the line passes through the point (10,80) meaning for every 10 x there is 80y
so you can just divide 80 by 10
Answer:
its 300 grams
Step-by-step explanation:
took the quiz
3) . Ddraw the radius to the right side of the chord. So you formed a right triangleNow let's apply Pythagoras
3.6² + 5.5²= x² ==> x = 6.57 ≈ 6.6
4) same logic but the other leg = x/2 you will find
x² = 133/4 & x =5.766≈ 5.8
5) arc ab = arc de (1st proposition)
