Solve A=S(1-DN) for N
PLS EXPLAIN HOW

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)

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

well

44-3-3-3=35

35+4+4+4+4=51

so the ansewr would be 51 degreesat 7: 00
