<h3>Answer: C) none of the equations are identities</h3>
If you plugged theta = 0 into the first equation, then you would have
sin(45) + cos(45) = sin(0) + cos(0)
sqrt(2) = 1
which is a false equation. We don't have an identity here.
The same story happens with the second equation. Plug in theta = 0 and it becomes
cos(60) - sin(60) = cos^2(0) + tan(0)
1/2 - sqrt(3)/2 = 1 + 0
-0.37 = 1
which is false.
The answer is 8
I hope this helps!
IM THINKING B.)
HOPE ITS RIGHT LOL
Answer is <span>a) line BC is congruent to line CD
this is not true
BC should be </span>congruent to line EC, not CD
