Answer:

∠  ABC = 75°

Step-by-step explanation:

using the sine ratio in right  Δ ABD

sin ABD = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AD}{AB}[/tex] = [tex]\frac{4}{8}[/tex] = [tex]\frac{1}{2}[/tex] , then

∠ ABD = [tex]sin^{-1}[/tex] ( [tex]\frac{1}{2}[/tex] ) = 30°

Using the sine ratio in right Δ CBD

sin CBD = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{CD}{BC}[/tex] = [tex]\frac{3}{3\sqrt{2} }[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] , then

∠ CBD = [tex]sin^{-1}[/tex] ( [tex]\frac{1}{\sqrt{2} }[/tex] ) = 45°

Then

∠ ABC = ∠ABD + ∠ CBD = 30° + 45° = 75°

Answer:

138°

Step-by-step explanation:

X = 180° - 42° [Sum of angles in a triangle]

X = 138°

Answer: 48 degrees.

Step-by-step explanation: The key to finding a missing interior angle is to have all the angles add up to 180.  The corner with the square means that the angle is 90 degrees.  An angle has been provided, which is 42 degrees. Now, we can add 42 and 90, and you have 132 degrees so far. Now, we need to subtract 132 from 180 and we have 48 degrees. That is your value of x.

Have a great day! :)

Answer:

A 48 degrees B 88 degrees C 44 degrees

Step-by-step explanation:

All the sides of a triangle add up to 180 degrees.

Subtract the known side from 180. 180-48=132 degrees. That means 132 degrees is the total size of the unknown two angles. You can write that like this:

132=x+(x-44)

Simplify

132=2x-44

add 44

176=2x

Divide by 2

x = 88 degrees.

Now we know that angle B is 88 degrees. Now we just have to find angle C, which will be simple now that we know what x equals.

X-44

88-44

44 degrees

Answer:

7x-14=2x+11

Step-by-step explanation:

Collect like terms

7x-2x=11+14

5x=25

Divide both sides by the coefficient of x(5).

x=25/5

x=5

Answer:

x=5

Step-by-step explanation:

The first thing we need to do in this equation is to get both of the x variables on the same side.

How do we do this you might ask? Well, need to cancel out the 2x so all we have left is one x variable. We can do this by subtracting 2x from each side.

The important thing to remember when solving equations like these is that whatever you do to one side, you MUST do to the other side.

2x-2x is 0 so that cancels out the 2x on the right side. 7x-2x=5x so we are left with that for our left side.

Now, we have to get rid of the constants (the non-variable numbers)

Let’s cancel out the 14 on the left side so the x is still by itself.

Add 14 to -14 to cancel it out. Do the same to the right side. 14+11=25 so that 25 is what we are left with on the right side.

Our equation becomes 5x=25

Now we have to completely isolate the x with no coefficient. We do this by dividing 5 by each side. But remember the rule, whatever you do to one side, you must do to the other. So we divide 25 by 5 as well.

5x/5 is x and 25 divided by 5 is 5

So our final answer is…

X=5

Answer:

(x, y) -> (2.5x, 2.5y)

Step-by-step explanation:

To find which equation is correct, first, let's find a similar point of Figure J and Figure K.

As you can see, Figure J was enlarged by a SF of 2.5 because -3 x 2.5 = -7.5, and -2 x 2.5 = -5.

Therefore, the answer is (x, y) -> (2.5x, 2.5y).

Answer:

  x + y = 11

Step-by-step explanation:

The perpendicular bisector goes through the midpoint of the segment and has a slope that is the opposite reciprocal of the slope of the segment. The midpoint is ...

  M = (A+B)/2 = ((6, 9) +(2, 5))/2 = (6+2, 9+5)/2 = (8, 14)/2

  M = (4, 7) = (Mx, My)

The slope can be found from the differences of the coordinates of the two points:

  (Δx, Δy) = (2 -6, 5 -9) = (-4, -4)

Factoring out -4, this becomes

  (Δx, Δy) = (1, 1)

__

These values can be used directly to form the equation of the perpendicular line:

  (Δx)(x -Mx) +(Δy)(y -My) = 0

  1(x -4) +1(y -7) = 0

  x + y = 11 . . . . . . . . . add 11 and simplify

___

Additional comment

Using "standard form" for the equation, we don't actually need the value of the slope. If you were to use point-slope form or slope-intercept form for the equation of the line, then you would need to know the slope of the segment is ...

  m = Δy/Δx = 1/1 = 1

and the slope of the perpendicular is ...

  m' = -1/m = -1/1 = -1

Answer:

3

Step-by-step explanation:

Factors of 15:   1, 3, 5, 15

Factors of 6x:  1, 2, 3, 6, x

Therefore, the greatest common factor (the highest factor that they both share) is 3

Factor = f

——————

f15 = 1, 3, 5, 15

f6 = 1, 2, 3, 6, x

So the answer is 1 and 3, but we need to give the answer from the highest number. The highest number is 3.

Answer:

D

Step-by-step explanation:

36x² - 49 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b)

then

36x² - 49

= (6x)² - 7²

= (6x - 7)(6x + 7)

Thus 6x - 7 is a factor of the expression

We need to simplify the expression 36x² - 49 , but let's recall the identity which is the main key to solve this question i.e

So , here we can write the above expression as

[tex]{:\implies \quad \sf (6x)^{2}-(7)^{2}}[/tex]

Now , using the above identity this can be written as :

[tex]{:\implies \quad \sf (6x-7)(6x+7)}[/tex]

So , here both (6x-7) and (6x+7) are factors of 36x²- 49 , but in the options their is only 6x - 7.

Hence , Option D) 6x - 7 is correct

As here , 36x² = (6x)² = a² , so a = 6x and as 49² = 7² = b² , so b = 7
