Mary states, "lf the diagonals of a parallelogram are congruent, then the parallelogram is a rectangle." Decide if her statement is true or false.
O A. True
O B. False

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

none of these

23 + 34 add up to 57 so just inform the teacher of this really stupid mistake
