The required value of tan(7π/12) = √[(2+√3)/(2-√3)].
To find the exact value of tan(7π/12).
What are trigonometric equations?These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operation.
[tex]tanx =\sqrt{ \frac{1 -cos2x}{1 + cos2x} }[/tex]
tan(7π/12) = √ [ (1 - cos2(7π/12) ) / (1 + cos2(7π/12) ]
= √ [ (1 - cos(7π/6) ) / (1 + cos(7π/6) ]
= √ [ (1 - cos(π + π/6) ) / (1 + cos(π + π/6) ]
Since cos(π + x) = -cosx
= √ [ (1 + cos(π/6) ) / (1 - cos(π/6) ]
Here, cos( π/6 ) = √3/2
= √ [ (1 + √3/2 ) / (1 - √3/2 ]
= √ [ (2 + √3)/2 / (2- √3)/2 ]
= √ [ (2 + √3) / (2- √3) ]
Thus, the required value of tan (7π/12) = √ [ (2+√3)/(2-√3) ].

the answer is number a 88 CM square
hey, if the volume is 8cm^3, each side will be 2 cm, why? because 8√3 equals 2. or 8=2×2×2.
so each side equals 2.
to calculate the surface area, we need to calculate one square's area and multiples it by the number of the surfaces.
to calculate a square's area: 2×2=4
so each square has the surface of 4cm^2
now we count to see how many squares do we have.
we've got 22 surfaces.
so 22×4=88cm^2
then option C is the answer

Find the total surface area of the rectangular prism in square millimeters. 2cm 6 cm 9cm
==============================================
Work Shown:
L = 2 = lengthW = 6 = widthH = 9 = heightThe order of length, width and height doesn't matter
SA = surface area of rectangular prism
SA = 2*(LW + LH + WH)
SA = 2*(2*6 + 2*9 + 6*9)
SA = 2*(12 + 18 + 54)
SA = 2*(30+54)
SA = 2*(84)
SA = 168 square cm

The blueprint of a deck has a scale of 2 centimeters equals 9 feet. The scale drawing is shown below
I have part A I need help with b
Part B
Decking costs $1.75 per square foot. How much will it cost to build the deck?
Complete question is;
The blueprint of a deck has a scale of 2 centimeters equals 9 feet.
A) What are the actual lengths of the sides of the deck?
B) Decking costs $1.75 per square foot. How much will it cost to build the deck?
Answer:
A) actual lengths are;
27 ft, 36 ft and 45 ft
B) cost of entire deck = $850.5
Step-by-step explanation:
A) From the attached image, we see that the sides of the triangle deck are;
8cm, 10cm and 6 cm
Now, we know that 2cm represents 9 ft.
Thus;
8cm will be; 8 × 9/2 = 36 ft
10 cm will be; 10 × 9/2 = 45 ft
6 cm will be; 6 × 9/2 = 27 ft
Thus, actual lengths are;
27 ft, 36 ft and 45 ft
B) Area of deck is Area of triangle = ½ × base × height.
In this diagram, base = 6 cm = 27ft
Height = 8 cm = 36 ft
Thus;
Area of deck = ½ × 27 × 36
Area of deck = 486 ft²
We are told that the Decking costs $1.75 per ft²
Thus;
Cost of entire deck = 1.75 × 486 = $850.5

Mustafa’s soccer team is planning a school dance as a fundraiser. The DJ charges $200 and decorations cost $100. The team decides to charge each student $5.00 to attend the dance. If n represents the number of students attending the dance, which equation can be used to find the number of students needed to make $1,500 in profit?
5n – 300 = 1,500
5n + 300 = 1,500
5n – 200 + 100n = 1,500
5n – 100 – 200n = 1,500
Answer:
The first one, A
Step-by-step explanation:
DJ costs $300 in total.
For every student there is $5.
We want a profit of 1,500, so the total money earned from students attending subtracted by the costs of the DJ should be 1,500.
5n - 300 = 1,500
For the second one, it'll be the DJ giving you $300.
The last Two answers has an n where it's supposed to be money when n represents each student.
Answer:
it would be A
