Answer: Alternate interior angles have the same measure. As we know that 'angle 1 ' and 50° are alternate interior angles hence they must be equal. Also we now that sum of all the angles of a triangle is equal to 180°. Hence, m∠2=15°.

Step-by-step explanation:

28

The outlier would be 28 because it is much lower than the rest of the numbers in the group and removing it would make the mean increase.

Step-by-step explanation:

ABC and DBE = Vertical

DBC and ABC = Adjacent

CBD and EBA = Vertical

EBA and ABC = Adjacent

Adjacent angles are two angles that have a common vertex and a common side but do not overlap.

Vertical angles are angles opposite each other where two lines cross.

Answer:

12

Step-by-step explanation:

it will be 12 inches greater

The volume of the front door is 72 cubic inches greater than the volume of the bedroom door.

A rectangle is a 2-D shape with length and width.

The length and width are different.

If the length and width are not different then it is a square.

The area of a rectangle is given as:

Area = Length x width

We have,

Assuming that the bedroom door has the same height as the front door, we can use the formula for the volume of a rectangular solid to calculate the volume of each door.

Let L, W, and H be the length, width, and height of the front door, and let L' and W' be the length and width of the bedroom door.

We know that Lx W = 72 (since the area of the base is 72 square inches), and L' x W' = 60 (since the area of the base is 60 square inches).

The volume of the front door is given by V = LWH.

The volume of the bedroom door is given by V' = L'*W'*H.

Since the height is the same for both doors, we can divide V by V' to get the ratio of the volumes:

V/V' = (LWH)/(L'*W'H)

V/V' = (LW)/(L'*W') (canceling out the heights)

Substituting in the given values, we get:

V/V' = (72)/(60)

V/V' = 6/5

This means that the volume of the front door is 6/5 times the volume of the bedroom door.

To find the difference in volume, we can subtract the volume of the bedroom door from the volume of the front door:

V - V' = (6/5)*V' - V'

V - V' = (1/5)V'

V - V' = (1/5)(L'*W'*H)

Substituting in the values for L', W', and H, we get:

V - V' = (1/5)*(L' x W' x H)

V - V' = (1/5)(√(60) x √(60) x H)

V - V' = (1/5) x 360

V - V' = 72

Therefore,

The volume of the front door is 72 cubic inches greater than the volume of the bedroom door.

Step-by-step explanation:

Im assuming that 15 is the hyp. of the triangle.

Multiply 9 twice and 15 twice

Then subtract 225-81 and you get 144. Find the square root and you get 12.

Answer:2x+15+6x-37/2=3x+5

We move all terms to the left:

2x+15+6x-37/2-(3x+5)=0

We add all the numbers together, and all the variables

8x-(3x+5)+15-37/2=0

We get rid of parentheses

8x-3x-5+15-37/2=0

We multiply all the terms by the denominator

8x*2-3x*2-37-5*2+15*2=0

We add all the numbers together, and all the variables

8x*2-3x*2-17=0

Wy multiply elements

16x-6x-17=0

We add all the numbers together, and all the variables

10x-17=0

We move all terms containing x to the left, all other terms to the right

10x=17

x=17/10

x=1+7/10

The value of RS is 31.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

If RS and UT are parallel, then their corresponding sides are proportional. Thus,

RS/UT = (2x + 15)/(6x - 37)

Now,

RS/UT = (2x + 15)/(6x - 37)

Cross-multiplying.

(2x + 15)UT = RS(6x - 37)

Expanding and simplifying.

2xUT + 15UT = 6xRS - 37RS

Rearranging.

6xRS - 2xUT = 15UT + 37RS

Factorizing.

2x(3RS - UT) = 15UT + 37RS

Dividing both sides by (3RS - UT):

2x = (15UT + 37RS)/(3RS - UT)

Substituting RS = 2x + 15 and UT = 6x - 37:

2x = (15(6x - 37) + 37(2x + 15))/(3(2x + 15) - (6x - 37))

Simplifying

2x = (90x - 555 + 74x + 555)/(6x + 36)

2x = (164x)/(6x + 36)

Multiplying both sides by (6x + 36):

12x² + 72x = 164x

Simplifying

12x² - 92x = 0

Factoring out 4x.

4x(3x - 23) = 0

So,

x = 0 or x = 23/3.

Since x cannot be 0 (as it would make UT = -37, (which is not possible),

x = 23/3.

Substituting this value of x into RS = 2x + 15.

RS = 2(23/3) + 15 = 31

Thus,

The value of RS is 31.
