Hi, We know:
Sin(a + b) = 2.Sin(a).Sin(b)
Then,
= 2Sin(a).Cos(b)/Cos(a).Cos(b)
Canceling Cos(b)
= 2Sin(a)/Cos(a)
As Tan(a) = Sin(a)/Cos(a)
Then we will stay:
= 2Tan(a)
Or
= Tan(a) + Tan(a)
There is anything wrong on the alternatives
On the way to school, if the ratio of walkers to bus riders is 2:7, then the number of bus riders is 3.5 times the number of walkers.
Explanation:-
7 is 3.5 times larger than 2.
2*3.5 = 7
Answer: 3.5
Answer:
5
Step-by-step explanation:
Each triangle is a myriad of both |, ||, and |||.
Because BE = || and FE = ||| then BF = |
CD = 10 but thats equal to 2 | meaning that 1 | is 5.
Answer:
26/3
Step-by-step explanation:
x + 1/3 = 9
x = 9 - 1/3
x = 27/3 - 1/3
x = 26/3
For this case we must interpret the following expression algebraically:
"The quotient of a number and 8 is 16"
Let x be the variable that represents the unknown number.
Then we have the following expression:
![\frac {x} {8} = 16](https://tex.z-dn.net/?f=%5Cfrac%20%7Bx%7D%20%7B8%7D%20%3D%2016)
Clearing the variable "x":
![x = 16 * 8\\x = 128](https://tex.z-dn.net/?f=x%20%3D%2016%20%2A%208%5C%5Cx%20%3D%20128)
Answer:
![x = 128](https://tex.z-dn.net/?f=x%20%3D%20128)
