Answer:
Step-by-step explanation:
The first angle us (61x+3)
The second angle is (25x+5)
We use corresponding angles to get the top angle as a linear pair to (25x+5).
We use sum of angles on a straight line to obtain:
Group similar terms
We substitute to get:
Answer:
The mean and median are most likely the same or very close.
Step-by-step explanation:
Q2-Q1 = 12.5 - 11.5 = 1
Q3 - Q2 = 13.5 - 12.5 = 1
Data is almost symmetrical
It is 130 beats per minute.
Step-by-step explanation:
Just divide 1560 by 12.
A=3b+2
a-2=3b
(a-2)/3=b
therefore b=(a-2)/3
Step 1
The property of a parallelogram is that diagonals of a parallelogram bisect each other and hence have the same midpoint.
This means that the diagonals cut themselves into two equal halves.
Hence, they must have the same mid-points.
Therefore, if we prove that AC and BD have the same midpoint, then ABCD is a parallelogram.
Step 2
Find the midpoint of BD and AC
Since they have the same midpoint, the answer will be;
We Prove that AC and BD have the same midpoint which we have done. we know the diagonals of a parallelogram bisect each other; therefore, they have the same midpoint and ABCD is a parallelogram.
