For this case we have that by definition, a flat angle is the space between an intersection between two lines whose opening measures 180 degrees.

Then, if we look at the figure we have to:

2x + 3x = 180\\5x = 180\\x = \frac {180} {5}\\x = 36

Thus, the angle ABC is 2x = 2 * 36 = 72, less than 90 degrees, so it is an acute angle.

The CBD angle is3x = 3 * 36 = 108, greater than 90 degrees, so it is an obtuse angle.

ANswer:

x = 36

ABC is acute angle

CBD is obtuse angle

Answer:

x=36

Step-by-step explanation:

Angles on a line add to 180. You can combine 2x and 3x to get you 5x, making the complete unsolved equation 180=5x. If you divide both sides of the equation by 5, you will receive 36.

Solve 2w^2– 16w = 12W – 48 by factoring. Select the solution(s)
UkoKoshka [18]

Answer:

w=12 or w=2

Step-by-step explanation:

2w^2-16w=12w-48

2w^2-28w=-48

2w^2-28w+48=0

2(w^2-14w+24)=0

2(w-12)(w-2)=0

(w-12)(w-2)=0

w=12 or w=2

The greater of two numbers is six more
pickupchik [31]

Answer:

 

Let's begin by writing the mathematical equations given by the sentences.

 

Let X = smaller number

Let Y = larger number

 

The first sentence tells us

X + Y = 38

 

The second sentence tells us

X = Y/3 + 6

 

Since you weren't given a specific method to use, you can use either the substitution method or the elimination(addition) method, whichever works best for you.

 

Since the 2nd equation has the X isolated, I'm going to isolate the X in the first equation,

X = 38 - Y

 

Since both equations are equal to X, I can set them equal to one another and solve for Y.

Y/3 + 6 = 38 - Y

 

Y + 18 = 114 - 3Y

4Y = 96

Y = 24

 

Then use either of the two original equations to solve for X

X + Y = 38

X + 24 = 38

X = 14
