The best solution is,
tan(x)tan(x/2) = 1 - [(tanx + tanx/2 )/tan(3x/2)]
What is tangent function?One of the six fundamental functions in trigonometry is the tangent function. As stated, Tan A = Opposite Side/Adjacent Side is the Tangent Formula. Tangent may be modeled using sine and cosine as follows: Tan A = Sin A / Cos A.
Given:
tan(x)tan(x/2) = ?
We will use formula,
tanA×tanB = 1 - [(tanA + tanB )/tan(A+B)]
Substituting the values,
tan(x)tan(x/2) = 1 - [(tanx + tanx/2 )/tan(x+x/2)]
tan(x)tan(x/2) = 1 - [(tanx + tanx/2 )/tan(3x/2)]
Therefore, 1 - [(tanx + tanx/2 )/tan(3x/2)] is the solution.

Franco has 7/8 of an ounce of gold. He wants to give 3/16 of an ounce to his friend, Julie. He plans to divide the rest in half to make two rings. How much gold will he have for each ring. (answer with explanation will get Brainliest.)
Answer:
He will have 11/32 of an ounce for each of the two rings.
Step-by-step explanation:
He starts with 7/8 of an ounce.
He gives 3/16 of an ounce to Julie.
7/8 - 3/16 = 14/16 - 3/16 = 11/16
He now has 11/16 of an ounce left.
Now he divides 11/16 of an ounce in half.
(11/16) / 2 = 11/16 * 1/2 = 11/32
He will have 11/32 of an ounce for each of the two rings.

Gift shop sales ($) 200 250 300 350 400 450 What percent of the time did the gift shop have sales of $350 or less? %
Answer:
Step-by-step explanation:

100(4/6)=400/6=[tex]66\frac{2}{3}\% $ or rounded to 66.67% $ [/tex]
The percentage of the time did the gift shop have sales of $350 or less should be considered as the 66.67%.
Calculation of the percentage:Sinceas we can see that there are total 6 things out of which 4 should be within 350 or less than 350
So here the percentage be like
[tex]= 4\div 6[/tex]
= 66.67%
Hence, The percentage of the time did the gift shop have sales of $350 or less should be considered as the 66.67%.

Step-by-step explanation:
When x = -1, the equation is 5(-1) - 8y = 29. This simplifies to -5 - 8y = 29. Add 5 to both sides to get -8y = 34. Divide -8 from both sides to get y = -4.25.

18% of the the students at a school are in year 8 and 16% of the students are in year 9. If the school has 126 tera 8 students, determine the number of year 9 students.
Answer:
112
Step-by-step explanation:
The general form of all percentage questions is: the chunk= (some percentage) (of the whole), or c=p*w
We know that 18% of students are 8th grade and that is 126 students, so p = 0.18 and c=126 (126 students are 18% of the whole school)
126 = (0.18)w, divide both sides by 0.18
126/(0.18) = w = 700
9th graders are 16% of the school or 16% of 700 students
c = (0.16) 700 = 112 students
