Trapezoid ABFE is similar to trapezoid EFCD. What is the length of DC?

Answers

Answer 1

Answer:

6.75

Step-by-step explanation:

Find the relationship between the trapezoids. You can see that the top of trapezoid ABFE is 3 units and the top of EFCD is 4.5 units. 3 * 1.5 = 4.5, so t the sides of trapezoid EFCD are 1.5 times more than the sides of ABFE.

Now, you know the bottom of ABFE is 4.5, so the bottom of EFCD is 1.5 times longer because they are proportional, so you can do 4.5 * 1.5 = 6.75 units.

dexter needs to find each angle in this figure that is adjacent to (the second question)

Answers

It would be MOP is adjacent

The Adjacent angle to <LON are <NOP, <NOK and <LOK.

What are adjacent angle?

When two angles share a shared vertex and side, they are said to be neighbouring angles. The vertex of an angle is the terminal of the rays that create the sides of an angle. When two adjacent angles have a common vertex and side, they might be complimentary or supplementary angles.

Now, the adjacent angle to <LON are <NOP, <NOK and <LOK.

Dexter claim is wrong because <MON is not adjacent to <LON, <MON is just a part of <LON.

and, the part of an angle cannot be considered as Adjacent angle.

what is 2/3 of 16 (please and thank you)

Answers

Answer:

10.6

hope dis helps ^-^

The requried value of 2/3 fraction of 16 is 10 and 2/3, or approximately 10.67.

To find 2/3 of 16, you can multiply 16 by the fraction 2/3:

(2/3) * 16 = (2 * 16) / 3

Now, calculate the numerator:

2 * 16 = 32

So, the result is:

(2/3) * 16 = 32 / 3

Next, simplify the fraction:

(2/3) * 16 = 10 and 2/3 or 10.67 (rounded to two decimal places)

Therefore, 2/3 of 16 is 10 and 2/3, or approximately 10.67.

start with this equation:

26-x=14

it's best to make the x variable positive at all times.

to do that, you need to make everything else positive.

-26+x=-14
