Answer:
tanΘ = - 
Step-by-step explanation:
Using the trigonometric identities
• sin²x + cos²x = 1, hence
cosx = ± √(1 - sin²x )
• tanx = 
given sinΘ = 
, then
cosΘ = ± 
Since Θ is in the second quadrant where cosΘ < 0, then
cosΘ = - 
= - 
= - 
tanΘ = 
= × - 
= -
Answer:
10 months
Step-by-step explanation:
my answer is 10 months because i added 30 and 18 together to get 1.6666666666666667 then i divided by 6, because i added 1 and 5 together, and got 10.
Answer:
0.9
Step-by-step explanation:
4/3 by 1.5
to divide 4/3, we have to convert it to decimal too
so 4/3 = 1.333 repeatedly
4/3 by 1.5=1.333/1.5
0.8886
0.9 approximately
The answer is y = -13/7 + 3x/7
Y=x/5
divide 5 on both sides, this is as far as you can simplify the equation with the information given
