Answer:
-(√5)/3
Step-by-step explanation:
The tangent being negative means the sine and cosine have opposite signs. Using the identity ...
cos(o) = ±√(1 -sin(o)^2)
we find ...
cos(o) = -√(1 -(2/3)^2) = -√(5/9)
cos(o) = -(√5)/3

Are you looking for knowledge prior to precalculus or before calculus 1?
Double every year
year one
4 times 2
year 2
4 times 2 times 2 aka 4 times 2^2
year 3
4 times 2 times 2 times 2 aka 4 times 2^3
obviously
at year 'n' the number of rabbits will be
4 times 2^n
Answer:
JK = 20
Step-by-step explanation:
Angle Bisector Theorem: an angle bisector of a triangle divide the opposite side into two segments that are proportional to the other two sides of the triangle
LK / JK = LM / JM
(45 - JK) / JK = 75 / 60 = 5 / 4
5 JK = 4 (45 - JK)
5 JK = 180 - 4 JK
9 JK = 180
JK = 20
