X divides into the line PQ in the ratio 2:3 P is (2,1) and Q is (12.5,7.5) work out the coordinates of point X
Lyrx [107]
According to ratio theorem;
x = 2/5(Q) + 3/5(P)
   = 2/5(12.5,7.5) + 3/5(2,1)
   = 2( 2.5, 1.5) + 3( 0.4, 0.2)
   = (5,3) + (1.2,0.6)
   = (6.2, 3.6)
The Coordinates of X will be;
  =(6.2, 3.6)

The figure below shows a rectangle ABCD having diagonals AC and DB:
Kisachek [45]

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.
