Answer:
Step-by-step explanation:
In a rectangle, diagonals are equal and bisect each other
BE = AE
6x - 5 = 2x + 7
6x - 2x - 5 = 7
4x - 5 = 7
4x = 7 + 5
4x = 12
x = 12/4
x = 3
AE = 2x + 7
= 2*3 + 7
= 6 + 7
AE = 13
AC = 13 + 13
AC = 26
m∠EBC = 50
In rectangle, each angle is 90
m∠ABE + m∠EBC = 90
m∠ABE + 50 = 90
m∠ABE = 90 - 50
m∠ABE = 40
In rectangle, AB // DC and DB transversal
m∠ECD = m∠ABE { alternate interior angles}
m∠ECD = 40
Answer: 85
Step-by-step explanation:
Add all the numbers together than
divide by 8
Answer:
A parallelogram
Step-by-step explanation:
The opposite sides and angles are congruent.
2nd one, take area of whole 12 x 4=48, if area is equally divided, divide area by 2 or multiply by 1/2
Your answer is -3r + 137
thats the answer i think
