Its what the other guy said he is right
Answer:
1-cos2A/sin2A
=(1-cos^2 A+sin^2 A)/(2sinAcosA)
=(sin^2 A+sin^2A)/2sinAcosA
=2sin^2 A/2sinAcos^2 A
=sinA/cosA
=tanA
Answer:
Diameter=9
Radius=4.5
Step-by-step explanation:
Because they are s t u p i d and they are slow teachers.They don't want us to learn any thing.
X= 5.1x+11.3
