Answer:
c
Step-by-step explanation:
Answer:
Step-by-step explanation:
To do this, we must use the unit circle. At the angle 
the coordinate pair is (
, 
) and the hypotenuse is 1
Now that we know these we can start using the trig functions
sin = y
cos = x
tan = 
And the other functions would be the reciprocal of these
csc = 
sec = 
cot = 
This would mean that
sinx =
cosx =
tanx =
or 
if you're supposed to rationalize your denominators
cscx = 2
secx = 
or 
cot = 
Answer:
c = -13.78.
Step-by-step explanation:
21.2x + c ≡ 5.3(4x - 2.6)
21.2x + c ≡ 21.2x - 13.78
Equating constant terms:
c = -13.78.
Answer: 4.5
Step-by-step explanation:
do the numbers that are in parentheses first which is 2+6=8 next is 5+3=8 then add both ur answers together then divide that by 4 which should equal 4.5
