which of the following best explains why mc021-1.jpg?

Option D is correct.

The best explanation for the following ≠   is; The angles do not have the same reference angle or the same sign.

Explanation:

Why: ≠  

*Every trigonometry function is positive in the first quadrant.  

*In second quadrant only sin is positive and its inverse cosec. Rest all the function are negative.

*In third quadrant gives positive value only for tan and its inverse i.e cot

*In fourth quadrant gives positive value only for cos and its inverse sec.

The value of   = -0.57735026919

and the value of   = -1.73205080757.

therefore, the values of ≠  .

Also,

the angle lies in the second quadrant and the angle lies in the fourth quadrant.

Hence, the angles do not have the same reference angle or the same sign.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
