Perimeter of figure EFGH=10,because they say that figure ABCD is similar t
o figure EFGH.Side BC is twice bigger than side FG and by knowing that it means that the perimeter of figure EFGH is half of the perimeter of figure ABCD,which is 20/2 and that gives 10.I hope it helped.. :-)

Frankie solved the math problem below. Find the error in Frankie's work and explain it in words, using math language. 2 1/3 - 1
HACTEHA [7]

Given:

The expression is

2\dfrac{1}{3}-1\dfrac{2}{5}

To find:

The error in Frankie's work.

Solution:

We need to simplify 2\dfrac{1}{3}-1\dfrac{2}{5}, so

2\dfrac{1}{3}=2\dfrac{1}{3}\times \dfrac{5}{5}

2\dfrac{1}{3}=2\dfrac{5}{15}

and,

1\dfrac{2}{5}=-1\dfrac{2}{5}\times \dfrac{3}{3}

1\dfrac{2}{5}=-1\dfrac{6}{15}

Now,

2\dfrac{1}{3}-1\dfrac{2}{5}=2\dfrac{5}{15}-1\dfrac{6}{15}

2\dfrac{1}{3}-1\dfrac{2}{5}=(2+\dfrac{5}{15})-(1+\dfrac{6}{15})

2\dfrac{1}{3}-1\dfrac{2}{5}=2+\dfrac{5}{15}-1-\dfrac{6}{15}

2\dfrac{1}{3}-1\dfrac{2}{5}=1-\dfrac{1}{15}

2\dfrac{1}{3}-1\dfrac{2}{5}=\dfrac{14}{15}

Therefore, there is error in Frankie's last step. In that step, he did not subtract the mixed fraction correctly.

The measure of the complement of the supplement of angle A is 28°. The measure in degrees of angle A is​
Airida [17]

You can put this solution on YOUR website!

Define your variables,

Let X be your Angle

Then 180 - X is your Supplement

and 90 - X is your complement

Now you need to put these into an equation, this particular word probled does not have the equal sign "IS" however, the word measure0-xs, is the same, so that is where your = sign will go.

Your Equation should be...

180-x=2*(90-x)+28

Distribute

180-x=180-2x=28

Subtract 180 From Both Sides and add 2X to Both Sides

X+=+28

Your angle is 28, the Supplement is 152 and your Complement is 62

Please help me with number 19
eimsori [14]
The new equation will be (x-1)² + (y-18)²=36

2) x²+y²+6x+12y=4
(x²+6x+?)-(?) + (y²+12y +??) -(??)=4

(x²+6x+9)-(9) + (y²+12y +36) -(36)=4
(x+3)² - 9 + (y+6)² - 36 = 4

(x+3)² +(y+6)² = 49
