Take DEBC a parralelogram
Parralel sides are DE and BC
THEREFORE,
1/2*(a+b)*h
1/2*(6+15)*h
1/2*(21)*h=0
10.5*h=0
h=-10.5

Find the value of x and y.

NeX [460]

Answer:

x = 4, y = 2

Step-by-step explanation:

Given quadrilateral is a parallelogram. Diagonals of a parallelogram bisects each other.

$\therefore \: 3x = 12 \\ \therefore \: x = \frac{12}{3} \\ \huge \red{ \boxed{\therefore \: x =4}} \\ \\ \therefore \: 4y = 8 \\ \therefore \: y = \frac{8}{4} \\ \huge \purple{ \boxed{\therefore \: y =2}} \\$

**************find x

slavikrds [6]

Answer:

x = 6

Step-by-step explanation:

2/(x-2) = 5/(4+x) - set up the ratios of similar sides

2(4 + x) = 5(x - 2) - cross multiply to solve

8 + 2x = 5x - 10 - simplify

18 = 3x - simplify to get x on one side of the equation

6 = x - divide both sides of the equation by 3 to isolate x

An assembly line worker at rob bicycle factory adds a seat to a bicycle at a rate of 2 seats every 12 minutes write and solve a

Arturiano [62]

Answer:

6N = T

They will take 96 minutes to add 16 seats.

Step-by-step explanation:

In the factory, the workers add bicycle seats at a rate of 2 seats every 12 minutes.

If the number of seats they add is N and the number of minutes it takes is T, then they are proportional i.e. N ∝ T.

⇒ N = kT ........... (1)

Now, N = 2 for T = 12 minutes.

So, from equation (1), 2 = 12k

⇒ $k = \frac{1}{6}$

Therefore, the equation (1) becomes $N = \frac{1}{6}T$

⇒ 6N = T ......... (2)

Now, for N = 16, from equation (2) we get,

T = 16 × 6 = 96 minutes.

Therefore, they will take 96 minutes to add 16 seats. (Answer)

Write a complete two-column proof for the following information. Hint: Use the Angle Addition Theorem and the fact that a line i

kramer

Answer:

Step-by-step explanation:

Given: m∠1 = 62° and lines t and l intersect

Prove: m∠4 = 62°

Proof:

Statement Reason

m∠1 = 62° Given

m∠1 , m∠2 are supplementary t is a straight line hence linear pair.

m∠4 , m∠2 are supplementary r is a straight line hence linear pair.

Angle 2=180-62 = 118 Definition of supplementary angles

Angle 4 = 180-118 =62 -do-

Angle 1 = Angle 4 Equality property

Hence proved
