Step-by-step explanation:
Step-by-step explanation:
81×1/4
=20.24
this is the answer
Answer:
1, 4, and 5
Step-by-step explanation:
1 is correct because 5*5=25*4=100
2 is incorrect because 5*5=25*5=125
3 is incorrect because 5*4=20*4=80
4 is correct because 5*20=100*1=100
5 is correct because 5*2=10*10=100
6 is incorrect because 5*10=50*10=500
Remark
You need to start with three facts.
x and y are complements which means that x + y = 90
Sin(x) = cos(90 - x)
<CPN = <DPN Definition of a bisector.
From the 3 facts above, we can gather than
CPN + y = 90
Therefore the cos of CPN = Sin(y)
