Complementary angles are angles that add up to 90 degrees. 2x is the first angle. Let y be the second one.
y+2x = 90
Subtract 2x from both sides.
y = 90 - 2x.
The second option is your answer. Have is nice day! :)
Answer:
Your welcomeeee :)
Step-by-step explanation:
When two variables correlate and when the value of one increases as the value of the other decreases we say the relationship between both variables shows a negative correlation
Answer:
2(n+3)-6
n=0
Step-by-step explanation:
2(3+n)-6=
Simplifying
2(3 + n) + -6 = 0
(3 * 2 + n * 2) + -6 = 0
(6 + 2n) + -6 = 0
Reorder the terms:
6 + -6 + 2n = 0
Combine like terms: 6 + -6 = 0
0 + 2n = 0
2n = 0
Solving
2n = 0
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Divide each side by '2'.
n = 0
Simplifying
n = 0
Answer:
49.4 degrees
Step-by-step explanation:
SOHCAHTOA
tan x = opposite / adjacent
tan x = 7 / 6
using graphing calculator, you get x = 49.398 round to tenth = 49.4 degrees
please give thanks :)
Answer: The level of the dose be after 3 hours= 0.03125 mg.
Step-by-step explanation:
General exponential decay equation : 
, where A = initial value , r= rate of decay , x =Time period.
Here, drug’s effectiveness is decreasing exponentially.
AS per given , we have
A= 250 mg
x=3
r= 95% = 0.95
Then, 
Hence, the level of the dose be after 3 hours = 0.03125 mg.
