X+4x = 180
5x = 180
x =180/5
x = 36
answer
D. 36
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 = 
= × - 
= -
So megan is four years younger than her aunt
m+4=a
or
m=a-4
the sum of their ages is at least 40
m+a<u>></u>40
subsitute a-4 for m
a-4+a<u /><u>></u>40
combine like terms
2a-4<u>></u>40
the answer is the third from the top
Hey there!
18 = -k + 3
-k + 3 = 18
-1k + 3 = 18
SUBTRACT 3 to BOTH SIDES
-1k + 3 - 3 = 18 - 3
SIMPLIFY IT!
-1k = 18 - 3
-1k = 15
DIVIDE -1 to BOTH SIDES
-1k/-1 = 15/-1
SIMPLIFY IT!
k = 15/-1
k = -15
Therefore, the answer is: k = -15
Good luck on your assignment & enjoy your day!
