4*3^2 = 36. Is that what you meant?
Answer:
ill give a guess because I cant read it
Answer:
Value of a is 26 and vaule of b is 12
Step-by-step explanation: May i get brainlesist
If <em>θ</em> lies in the fourth quadrant, then sin(<em>θ</em>) < 0 and cos(<em>θ</em>) > 0. So we have from the Pythagorean identity,
sin²(<em>θ</em>) + cos²(<em>θ</em>) = 1 ==> cos(<em>θ</em>) = +√(1 - sin²(<em>θ</em>)) = √21/5
Then
sec(<em>θ</em>) = 1/cos(<em>θ</em>) = 5/√21
and
tan(<em>θ</em>) = sin(<em>θ</em>)/cos(<em>θ</em>) = (-2/5)/(√21/5) = -2/√21
