Answer:
n = -6
Step-by-step explanation:
Distribute the 2, to (n + 5) and you'll get 2n + 10 = -2. Then subtract the 10 from both sides, and you' get, 2n = -12. Then divide -12 by 2 and you get -6 as your final answer.
Answer:
The value of Tan (a + b) is .
Step-by-step explanation:
Given as :
Tan b =
Sin a =
∵Sin Ф =
So, =
Now, Base² = Hypotenuse² - Perpendicular²
Or, Base² = 13² - 12²
Or, Base² = 169 - 144
Or, Base² = 25
∴ Base = = 5
And Tan Ф =
Or, Tan a =
Now, Tan (a + b) =
Or, Tan (a + b) =
or, Tan (a + b) =
or, Tan (a + b) =
Or, Tan (a + b) =
Hence The value of Tan (a + b) is . Answer
54.01 x 10^-2 , 5401 x 10^-4 , 5.401 x 10^-1 , 540.1 x 10^-3
These are the possible choices you can use to make this answer to a scientific notation.
Hope that helped!!
