How do I find the value of sec pi/12?

1 answer:

6 0

Sec x = 1/Cosx

Pi radians = 180 degress

Pi/12 = 180/12 = 15 degrees.

Sec15° = 1/Cos15°

Sec pi/12 = Sec 15° = 1/Cos 15°

Cos 15° = 0.9659 using a calculator.

Sec pi/12 = Sec 15° = 1/Cos 15° = 1/0.9659 = 1.0353

Sec Pi/12 = 1.0353

7. 3/5 = 4.5/x

3x= 5(4.5)

x = 15/2

8. 6/4 = 9/x

6x= 45

x= 15/2

8. since triangle ABC and ADE are identical,

angle E is also 30 degrees

so angle D = 180-(30+70)=80 degrees

9. 9/3 = x/5

3x = 45

x = 45/3 = 15

Is the given number a solution of an equation or inequality 3x-4=10;5

kotykmax [81]

The given number is not a solution of the equation i.e. the number is an inequality

<h3>How to determine the solution?</h3>

The equation is given as:

3x- 4 = 10

The number is given as:

This means that

x = 5

Substitute x = 5 in 3x- 4 = 10

3 * 5- 4 = 10

Evaluate the product

15- 4 = 10

Evaluate the difference

11 = 10

The above equation is not true i.e. the equation is actually an inequality

Hence, the given number is not a solution of the equation i.e. the number is an inequality
