Answer:

Step-by-step explanation:

sin A cos B-cos A sin B=sin (A-B)

sin (3x)cos (8x)-cos (3x)sin (8x)=sin (3x-8x)=sin (-5x)=-sin (5x)

Answer:

Its C i believe correct me if im wrong

Answer:

its 5-10

Step-by-step explanation:

did the quiz

4x + 20 = - 71 - ( 3x )

4x + 20 = - 3x - 71

Subtract sides minus 20

4x + 20 - 20 = - 3x - 71 - 20

4x = - 3x - 91

Add sides 3x

4x + 3x = - 3x + 3x - 91

7x = - 91

Divide sides by 7

7x / 7 = - 91 / 7

Simplification

x = - 13

Thus the number is ( - 13 ) .

Answer:

me no sabo

Step-by-step explanation:

Answer:

The possible pairs of sides are 90 and 120, 30 and 45, and 80 and 40.

Step-by-step explanation:

We know that 60 is a multiple of 15, 20, and 30, so we multiply by each factor to find all possible pairs: 10x6=60, 20x6=120, and 15x6=90, that gives your first pair, 90 and 120.

We have now multiplied our first factor, 6. Now we need to multiply our second factor, 3: 20x3=60, 15x3=45, and 10x3=30. That gives your second pair, 30 and 45.

Finally, we need to multiply by our 3rd factor, 4: 15x4=60, 20x4=80, and 10x4=40. That gives you your final possible pair, 80 and 40.

I hope this helps :-)

Answer:

The measure of the angle [tex]b[/tex] is approximately 44.040°.

Step-by-step explanation:

We need to apply Law of the Sine to determine the value of angle [tex]b[/tex], since the length of the side opposite to this side and another side length and its opposite angle are known. That is:

[tex]\frac{3.6}{\sin b} = \frac{5.1}{\sin 100^{\circ}}[/tex]

[tex]\sin b = \frac{3.6}{5.1}\times \sin 100^{\circ}[/tex]

[tex]b = \sin^{-1}\left(\frac{3.6}{5.1}\times \sin 100^{\circ} \right)[/tex]

[tex]b \approx 44.040^{\circ}[/tex]

The measure of the angle [tex]b[/tex] is approximately 44.040°.

Answer:

A. 4/13

B. Likely.

Answer:

D. 6

Step-by-step explanation:

90 - 30 = 60

so :-

10X = 60

then, X= 60÷10

X = 6.

[tex]\huge\text{Hey there!}[/tex]

[tex]\mathsf{10x^\circ = 90 - 30^\circ}[/tex]

[tex]\mathsf{10x^\circ = 60}[/tex]

[tex]\large\textbf{DIVIDE 10 to BOTH SIDES}[/tex]

[tex]\mathsf{\dfrac{10x}{10} = \dfrac{60}{10}}[/tex]

[tex]\large\textbf{SIMPLIFY it}[/tex]

[tex]\mathsf{x = \dfrac{60}{10}}[/tex]

[tex]\mathsf{x = \dfrac{60\div10}{10\div10}}[/tex]

[tex]\mathsf{x = \dfrac{6}{1}}[/tex]

[tex]\mathsf{x = 6}[/tex]

[tex]\huge\text{Therefore, your answer should be: }[/tex]

Answer:

An isosceles triangle has 2 equal sides. If the perimeter is 110 inches, and your base is 34 inches, subtract the base from the total perimeter. 110-34= 76. If 2 sides have to be equal, the total length of the 2 sides is 76 inches, divide the 2 lengths by 2 to get the measure of each side individually. 76÷2=38.

Hence, your answer is each of the equal sides of the plate equals 38 inches.

Step-by-step explanation:

Answer:

x = 12

Step-by-step explanation:

We will be using pythagoras theorem.

Therefore, we will have: [tex]a^{2}[/tex] + [tex]x^{2}[/tex] = [tex]13^{2}[/tex]

Moreover, we have: [tex]a^{2}[/tex] = [tex]4^{2} + 3^{2}[/tex] => [tex]a^{2}[/tex] = 25

=> 25 + [tex]x^{2}[/tex] = 169

=> [tex]x^{2}[/tex] = 144 => x = [tex]\sqrt{144}[/tex] = 12

Answer:

Step-by-step explanation:

8-12=-4

Answer:

-4

Step-by-step explanation:

8-12=-4

Answer:

a) because of the distributive property when you distribute you get 2x+8=2x+8

b) because when you distribute, you get 3x+7=3x+21 which is not equal so no value of x will work

Answer:

a) 2x + 8 = 2(x + 4) has infinite solutions because it simplifies down to x = x. Here is the work where this equation is solved.

2x + 8 = 2(x + 4)

2x + 8 = 2(x) + 2(4)

2x + 8 = 2x +8

2x + 8 - 8 = 2x + 8 -8

2x = 2x

2x/2 = 2x/2

x = x

So, because the equation ends in x = x, you can substitute any value for x and the equation will remain true.

----------------------------------------------------------------------------------------------------------------

b) 3x + 7 = 3(x + 7) has no solutions because it simplifies down to an untrue statement. The equation is simplified below.

3x + 7 = 3(x + 7)

3x + 7 = 3(x) + 3(7)

3x + 7 = 3x + 21

3x + 7 - 7 = 3x + 21 - 7

3x = 3x + 14

3x/3 = 3x/3 +14

x = x + 14

However, this is false. x cannot be equal to itself plus 14.

x ≠ x + 14

The simplification of this equation is untrue, so there is no solution to it.
