In parallelogram abcd, point m is the midpoint of the side bc , point o is the intersection point of the segment am and diagonal bd . find the ratio bo: od.

BO:OD = 1:2

Step-by-step explanation:

Here, ABCD is parallelogram, point M is the midpoint of the side BC , point O is the intersection point of the segment AM and diagonal BD.

Let N is the mid point AB ⇒ AN=NB or 2.BN=DC.  ( because AB=DC)

And join Points N and C.   (by construction)

Then, In triangles NOB and DOC,

∠NOB=∠DOC  ( vertically opposite angles)

And, ∠OBN = ∠ODC ( By the property of interior alternative angles by same transversal)

Thus, By the property of similarity,

Therefore,   =

answer: what in the world is this

step-by-step explanation:

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
