Answer:Figure it out your self.
Step-by-step explanation:
Sin2(x) +cos(x)=1
from the relation: (sin2(x) +cos2(x) =1 )
so , sin2(x)=1-cos2(x)
by subs. in the main eqn.
1-cos2(x) + cos(x) =1
by simplify the eqn.
cos(x) -cos2(x)=0
take cos(x) as a common factor
cos(x)* (1-cos(x))=0
then cos(x)=0 && cos(x)=1
cos(x)=0 if x= pi/2
& cos(x) = 1 if x = 0 , 2*pi
so the solution is x= {0,pi/2 , 2*pi}
The answer is here. Hope I did help you.

Answer:
The length of AB = 17
Step-by-step explanation:
AB = √[(10-2)^2 + (4-19)^2]
AB = √(64 + 225)
AB = √289
AB = 17
