Answer:

AC = 3x + 3 (answers may vary)

Step-by-step explanation:

AB = 6x + 2

Answers may vary for this question,

Let's say that,

B = 4x + 1

So that means that,

A = 2x + 1

BC = 5x + 3

Since we chose

B = 4x + 1,

we must subtract B from BC to get C,

C = x + 2

Now we add A and C to get AC,

A = 2x + 1

C = x + 2

AC = 3x + 3

Solve for x:sinx+sin2x+sin3x=cosx+cos2x+cos3x in the interval 0≤x≤2π.

Solution

Verified by Toppr

We write the given equation as

(sinx+sin3x)+sin2x=(cosx+cos3x)+cos2x

or 2sin2xcosx+sin2x=2cos2xcosx+cos2x

or sin2x(2cosx+1)=cos2x(2cosx+1)

or (sin2x−cos2x)(2cosx+1)=0

∴sin2x−cos2x=0 or 2cosx+1=0

If sin2x−cos2x=0, then tan2x=1,

Hence 2x=nπ+π/4

or x=(4n+1)

.(1)

If 2cosx+1=0, then cosx=−1/2 (2)

∴x=2nπ±

2π

or x=

6n±2

We seek values of x in the interval 0≤x≤2π

In this interval (1) gives

x=π/8,5π/8,9π/8,13π/8. (n=0,1,2,3)

and (2) gives x=2π/3,4π/3. (for n=0,1)

Thus we get the answer

x=π/8,5π/8,2π/3,9π/8,4π/3,13π/8.

Help me please <br><br> will get rewared brainly if correct answer

larisa [96]

Well, split it into 3 shapes

21 x 10 = 210

3 x 6 = 18

2 x 6 = 12

210 + 18 + 12 = 240 square cm

Answer:

Step-by-step explanation:

p + n + d + q = 25

Put everything into quarters.

p and q are equally likely to be drawn

q + n + d + q = 25

There are 3 times as many nickels as quarters

n = 3q

q + 3q + d + q = 25

There is 25% more dimes than quarters.

d = 1.25 q

q + 3q + 1.25q + q = 25

6.25 q = 25

q = 25/6,25

=====================

q = 4

p = 4

d = 1.25 * 4 = 5

n = 12

Y= <br> Help me please thanks

MArishka [77]

The value of y will be equal to 4.61.

<h3>What is trigonometry?</h3>

Trigonometry is the branch of mathematics that set up a relationship between the sides and angle of the right-angle triangles.

The value of y will be calculated by using the Pythagorean theorem:-

a² + a² = (9√2)²

a = 9

Applying angle property in the triangle:-

$tan26 = \dfrac{MK}{9}$

9tan26 = MK

LM = 9 - 9tan26

LM = 9 - 4.38

LM = 4.62

Therefore the value of y will be equal to 4.61.
