Required

Write in mathematical notation

Using mathematical notation,in terms of n.

The given parameters can be rewritten as

and

The mathematical notation can be determined using:

So, we have:

answer: .75 km

step-by-step explanation:

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
