USING the cosine double-angle identity. About Transcript. The cosine double angle formula tells us that cos(2θ) is always EQUAL to cos²θ-sin²θ. For example, cos(60) is equal to cos²(30)-sin²(30). We can use this identity to rewrite expressions or SOLVE problems.

When the two lines intersected by the transversal are parallel, corresponding angles are congruent, alternate interior angles are congruent, alternate exterior angles are congruent, and consecutive interior angles BECOME supplementary, which means they have a SUM of 180 degrees.

ong>Answer:

let the no. at unit place is y

tens place is x

so the EQUATION is ACCORDING to QUESTION is 10x+y=8..............(i)

then we interchange the digits so the digits after interchanging is 10y+x

According to question,

10y+x=10x+y-54

9x-9y=54

9(x-y)=54

x-y=6.............(ii)

by adding equation (i) and (ii) we get:

x=14/11

ong>Answer:

there is no number which is DIVISIBLE by 13 and 25 except 1

3/4

Step-by-step EXPLANATION:

-3/8+x=-3/4

x=-3/4+3/8

x=-3/4

so 3/4 should be SUBTRACTED or -3/4 should be ADDED

so it is DIVISIBLE by 4

ong>Answer:

75 degree and it is a Scalene triangle

Step-by-step explanation:

We know that the Total sum of the angles of a triangle is 180.

We take the unknown side as x.

So, 45+60+x=180

105+x=180

x=180-105    (105 will come on the right side and become NEGATIVE)

x=75.

Since all SIDES are different it is a Scalene Triangle.

पता नहीं है खुद नहीं आता स्कूल में KYA पढ़ TA हो

ong>Answer:

These numbers from an A.P. with a = 4, d = 4

Let, 140 be the nth TERM of A.P.

∴ tn = 140

tn = a + (n – 1) d

∴ 140 = 4 + (n – 1) 4

∴ 140 = 4 + 4n – 4

∴ 140 = 4n

∴ n = 140/4

∴ n = 35

∴ 140 is 35 term of A.P.

Now, We have to find sum of 35 terms i.e. S35,

Sn = n/2[2a + (n – 1)d]

∴ S35 = 35/2 [2 (4) + (35 – 1) 4]

∴ S35 = 35/2[8 + 34 (4)]

∴ S35 = 35/2 [8 + 136)

∴ S35 = 35/2 [144]

∴ S35 = 2520

ong>Step-by-step explanation:

LET the THREE CONSECUTIVE multiples of 11 be,

x, (x+11), (x+22)

Therefore,

x+(x+11)+(x+22)=663

or, x+x+11+x+22=663

or, 3x=630

or, x=210

Since, x=210

Hence, x+11=221

and, x+22=232

ong>ANSWER:

hello BABY....................

I LOVE you

ong>Answer:

This is an easy step—easy to overlook, unfortunately. If you have a polynomial equation, put all terms on one side and 0 on the other. And whether it’s a factoring problem or an equation to solve, put your polynomial in standard form, from highest to lowest power.

For instance, you cannot solve this equation in this form:

x³ + 6x² + 12x = −8

You must change it to this form:

x³ + 6x² + 12x + 8 = 0

Also make sure you have simplified, by factoring out any COMMON factors. This may include factoring out a −1 so that the highest power has a POSITIVE coefficient. Example: to factor

7 − 6x − 15x² − 2x³

begin by putting it in standard form:

−2x³ − 15x² − 6x + 7

and then factor out the −1

−(2x³ + 15x² + 6x − 7) or (−1)(2x³ + 15x² + 6x − 7)

If you’re solving an equation, you can throw away any common constant factor. But if you’re factoring a polynomial, you must keep the common factor.

Example: To solve 8x² + 16x + 8 = 0, you can divide LEFT and right by the common factor 8. The equation x² + 2x + 1 = 0 has the same roots as the original equation.

Example: To factor 8x² + 16x + 8 , you recognize the common factor of 8 and rewrite the polynomial as 8(x² + 2x + 1), which is identical to the original polynomial. (While it’s true that you will focus your further factoring efforts on x² + 2x + 1, it WOULD be an error to write that the original polynomial equals x² + 2x + 1.)
