4. m1= 35
m2= 65
m3= 29
m4=115
m5=65
m6=36
m7=144
Those are the angles for question 4, i didnt know how to make the sign and Im not going to show work since that would take too long.

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:
Step-by-step explanation:
y intercept is 0, 15
x intercept is -40,0
15/40 = 3/8
y = 3/8 x + b
15 = b
y = 3//8x + b
