That θ−x is actually 180+2θ−x<span> with respect to x-axis

</span>When it emerges out, it should be 180−2θ+x<span> with respect to x.
</span>Considering our original x, the deviation is 180−2θ ... since it is in opposite direction, we should add 180 to it which makes <span>360−2θ

</span>

we take succesive images of every image on its opposite mirror till the image finally ends to the other side of the opposite mirror...

u should end up getting a arithmetic series for the angle for the image formed first 1 and i.this angle should not exceed 180 degree as the image will go behind the mirror..then the total no will be added for both to get the formula.

Find the exact value, without a
Ghella [55]

Answer:

√(2 + √3)/4

Step-by-step explanation:

Sine 5π/12 = Sine (5π/6)/2

Recall

π = 180°

Thus,

Sine (5π/6)/2 = Sine (5×180 /6)/2

= Sine 150/2

Recall

Sine θ/2 = √(1 – Cos θ)/2

Thus,

Sine 150/2 = √(1 – Cos 150)/2

But, Cosine is negative in the 2nd quadrant. Thus,

Cos 150 = – Cos 30 = –√3/2

Thus,

√(1 – Cos 150)/2 = √(1 – –√3/2 )/2

= √(1 + √3/2 )/2

= √[(2 + √3)/2 ÷ 2]

= √[(2 + √3)/2 × 1/2]

= √(2 + √3)/4

Therefore,

Sine 5π/12 = √(2 + √3)/4

Factor the expression 8x^3y-8x^2y-30xy
miv72 [106K]

Find the Greatest Common Factor (GCF)

GCF = 2xy

Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

2xy(8x^3y/2xy + -8x^2y/2xy + -30xy/2xy)

Simplify each term in parenthesis

2xy(4x^2 - 4x - 15)

Split the second term in 4x^2 - 4x - 15 into two terms

2xy(4x^2 + 6x - 10x - 15)

Factor out common terms in the first two terms, then in the last two terms;

2xy(2x(2x + 3) -5(2x + 3))

Factor out the common term 2x + 3

<u>= 2xy(2x + 3)(2x - 5)</u>
