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
11 1/3 since sunday’s total lemonade sold is 10 2/3 + 3 1/3 = 14 you subtract 2 2/3 from 14 which equals 11 1/3
Use Picture Math, i cant type in the other cause brainly doesn't accept it but it is Ga_thMath. (u)
x = hours and y = cost
y = 7.50 + (1.50) x { cost = 7.50 + (1.50 ) H }
