Answer:
32.9 units
Step-by-step explanation:
p/sinP = r/sinR
p = sinP × r/sinR
p = sin(64) × 21/sin(35)
p = 32.9069916

Answer: it’s D :)
Step-by-step explanation: I was wondering if you could help me with my recent chemistry question I’ve posted it over and over and nobody answered it seriously they only say random stuff for points or search it up but it’s not the right answer.. please help me if not that’s fine.
C since 25ab and 5ba both have the terms "a" and "b"
Since we don't have a figure we'll assume one of them is right and we're just being asked to check if they're the same number. I like writing polar coordinates with a P in front to remind me.
It's surely false if that's really a 3π/7; I'll guess that's a typo that's really 3π/4.
P(6√2, 7π/4) = ( 6√2 cos 7π/4, 6√2 sin 7π/4 )
P(-6√2, 3π/4) = ( -6√2 cos 3π/4, -6√2 sin 3π/4 )
That's true since when we add pi to an angle it negates both the sine and the cosine,
cos(7π/4) = cos(π + 3π/4) = -cos(3π/4)
sin(7π/4) = sin(π + 3π/4) = -sin(3π/4)
Answer: TRUE
