Question

In parallelogram LMNO, LM = 4.12, MN = 4, LN = 5, and OM = 6.4. Diagonals and intersect at point R. What is the length of ?

Answer 1

Answer:

The length of OR = 3.12

Step-by-step explanation:

In a parallelogram:

LM = 4.12

MN = 4

LN = 5 = 2.5 (divided by 2)

OM = 6.4

where LN and OM are diagonals. We will find the length of OR.

Now by applying the Pythagorean theorem:

b = √c²-a²

OR= √(4)²-(2.5)²

OR = √16-6.25

OR = √9.75

OR = 3.12

Thus the length of OR = 3.12 ...
