How to find exact value of tan 75°

Answers

Answer 1

Answer: $tan \alpha = (sin \alpha )/(cos \alpha ) \n--------\n\ntan75^0= \frac{\big{sin75^0}}{\big{cos75^0}} \n\nsin75^0=sin(45^0+30^0)=sin45^0\cdot cos30^0+sin30^0\cdot cos45^0=\n\n.\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ = ( √(2) )/(2) \cdot ( √(3) )/(2) + (1)/(2) \cdot( √(2) )/(2) = ( √(6)+ √(2) )/(4)$

Final answer:

To solve the equation 3x + 1 algebraically, subtract 1 from both sides and then divide both sides by 3. The solution is x = -1/3.

Explanation:

To solve the equation 3x + 1 algebraically, you need to isolate the variable x. Let's go step-by-step:

Subtract 1 from both sides of the equation: 3x + 1 - 1 = 0 - 1. This simplifies to 3x = -1.
Divide both sides of the equation by 3 to solve for x: $\frac{3x}{3} = \frac{-1}{3}$. This simplifies to x = -\frac{1}{3}.

So, the solution to the equation 3x + 1 = 0 is x = -\frac{1}{3}. This means that when you substitute x = -\frac{1}{3} into the equation, both sides will be equal.

Answers

How many yards of a carpeting that is 26 inches wide will be needed to cover a ﬂoor that
is 12ft by 13ft?

12ft = 144in
13ft = 156in

144in × 156in= 22464in²
(12ft) × (13ft) = (156ft²)

22464in² ÷ 26in = 864in needed
