Answer:

see explanation

Step-by-step explanation:

(15)

Since BE bisects ∠ ABD then ∠ DBE = ∠ ABE, thus

8x - 14 = 6x + 2 ( subtract 6x from both sides )

2x - 14 = 2 ( add 14 to both sides )

2x = 16 ( divide both sides by 2 )

x = 8

Thus ∠ ABE = 6x + 2 = 6(8) + 2 = 48 + 2 = 50°

(16)

Since BE bisects ∠ ABD then ∠ ABE = ∠ DBE = 12n - 8 and

∠ ABD = ∠ ABE + ∠ DBE, that is

22n - 11 = 12n - 8 + 12n - 8 = 24n - 16 ( subtract 24n from  both sides )

- 2n - 11 = - 16 ( add 11 to both sides )

- 2n = - 5 ( divide both sides by - 2 )

n = 2.5

Thus

∠ EBD = 12n - 8 = 12(2.5) - 8 = 30 - 8 = 22°

Write a subtraction sentence using integers.than,write the equivalent addition sentence and explain how to find the sum.please h
nata0808 [166]

Answer:

First option: 10 - (1) = 9

Second option: 10 - 5 + 4 = 5 + 4 = 9

Step-by-step explanation:

(10 -5) -4 = 5 - 4 = 1

Equivalent equation: 10 - 5 - 4 = 1

10 - (5-4) = there would be 2 ways to do this, you can either solve the equation in the bracket first or break it out. Because the sign before the bracket is minus so when you break it out, the minus sign in the bracket would become -- or equal to +

First option: 10 - (1) = 9

Second option: 10 - 5 + 4 = 5 + 4 = 9

Hope this help you:3

Ad libitum [116K]

Answer:

The next statements are are;

Statement                                                  {}        Reason

Segment \overline {DC} ≅ Segment \overline {AB}                        {}   CPCTC

\overline {AD} ≅ \overline {BC} and \overline {DC} ≅ \overline {AB}, therefore;

ABCD is a parallelogram                    {}               Parallelogram side theorem

Step-by-step explanation:

Statement                                                  {}        Reason

Segment \overline {DC} ≅ Segment \overline {AB}  by Congruent Parts of Congruent Triangles are Congruent (CPCTC)

Given that \overline {AD} ≅ \overline {BC} and we have that \overline {DC} ≅ \overline {AB}, we get;

ABCD is a parallelogram                    {}               Parallelogram side theorem

The parallelogram side theorem states that a quadrilateral is a parallelogram if it has two pairs or sets of congruent opposite sides.

A rug is shaped like a parallelogram with a base of 41⁄2 ft. and a height of 2 1⁄4 ft. What is the area of the rug? Draw and lab
Bess [88]

Answer:

46.125 square feet or 46\dfrac{1}{8} sq. feet.

Step-by-step explanation:

The rug is shaped like a parallelogram with a base of \frac{41}{2} = 20.5 feet. and a height of 2\dfrac{1}{4} = 2.25 feet.

Now, the area of a parallelogram is given by the product of one side as the base and the perpendicular distance of that side from the opposite parallel side as height.

Now, the area of the given parallelogram is (20.5 × 2.25) = 46.125 square feet. (Answer)
