The exact value of the given trigonometric function sin(140°)cos(20°) – cos(140°)sin(20°) is -√3/2.

Trigonometric functions are defined as the functions which show the relationship between the angle and sides of a right-angled triangle.

To find the exact value of sin(140°)cos(20°) – cos(140°)sin(20°), we can use the angle addition formula for sine:

sin(A+B) = sin(A)cos(B) + cos(A)sin(B)

We can use this formula to rewrite the expression as:

sin(140°)cos(20°) – cos(140°)sin(20°) = sin(120°+20°) - sin(120°-20°)

Then, using the angle addition formula for sine, we get:

sin(120°+20°) - sin(120°-20°) = sin(120°)cos(20°) + cos(120°)sin(20°) - sin(120°)cos(20°) + cos(120°)sin(20°)

This simplifies to:

2sin(120°)cos(20°) = 2sin(120°)cos(20°)

The value of sin(120°) is -1/2, and the value of cos(20°) is √3/2, so the final value of the expression is:

2(-1/2)(√3/2) = -√3/2

Answer:

Step-by-step explanation:

(x+4)² + y² = 1.5²

Answer:

115

Step-by-step explanation:

Answer: x = 115 degrees

Step-by-step explanation:

a triangle we know all angles had up to 180 degrees

for the first triangle we have 65 + 90 = 155 then we do 180 - 155 = 25

so for the small triangle one angle is 25 degrees

now for the other triangle we have 80 + 60 = 140 then 180 - 140 = 40

so now we have all angles except x and to find that we do 25 + 40 = 65 then to find x do 180 - 65 = 115

Answer:

36.7 I do believe Im not really sure though

Answer:

I believe it is 35.3

180-(90+27)

x/Sin63=18/Sin27

x=18Sin63/Sin27

x=35.3

Answer:

  y = -5x -1

Step-by-step explanation:

The 2-point form of the equation for a line can be useful.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (-11 -(-6))/(2 -1)(x -1) +(-6)

  y = -5/1(x -1) -6 . . . . . simplify a bit

  y = -5x -1 . . . . . slope-intercept form

Answer:

the ratio of boys to the total students is 15:27

Step-by-step explanation:

Since we know there are 15 boys and 12 girls, we can add those to know there are 27 total students. Therefore, the ratio it 15:27

Answer:

15:27

=5:9 (if answer is needed in simplest form)

Step-by-step explanation:

B  :  G   : Total

15 :   12 : 15+12=27

hence boys to total is 15:27

                                    =5:9 (if answer is needed in simplest form)

Answer:

The number of marbles of each color that should be present in the bag is;

1 red marble and 2 green marbles

Here, we note that the probability of a battery going dead = 1/3 and the

Therefore if the red marbles represent that a battery dies before 15 hours then the probability of picking the red marble should be 1/3. That is if there is only one red marble in the bag, the probability of picking the red will be 1/3 when there are other 2 green batteries in the bag

That is there should be 1 red marble and 2 green marble in the bag.

The ladder is 5.09 m long

Step-by-step explanation:

Given that,

The height of the wall, P = 5 m

The base of the ladder is 1 m away from the wall.

We need to find the length of the ladder. Let it is H. We can solve it using the Pythagoras theorem. It can be given by :

[tex]H^2=P^2+B^2\\\\H^2=5^2+1^2\\\\H^2=25+1\\\\H=\sqrt{26} \\\\H=5.09\ m[/tex]

So, the ladder is 5.09 m long.
