Answer:

64 units sqr.

Step-by-step explanation:

If the frame is 2 units wide, there is 4 units total on the top and bottom, extra. So, adding that to our units, it is 7+4 = 11 by 5+4 = 9 NINE BY 11. 9*11 = 99, and 99-35 = 64. So it is 64

Points C and D are equidistant from point A. Complete the following table to prove that AEC≅ AED

inna [77]

To prove that AEC≅ AED, we need to write following proofs or statement reasons.

It is given that points C and D are equidistant to point A. Hence,
AD ≅ AC

Next, CAE ≅ DAE. AE is the common side or the included side.

Then, AE ≅ EA by Reflexive Property of Congruence as it is congruent to itself.

Lastly, EAD ≅ EAC by Symmetric Property of Congruence as these triangles are mirror image of each other.

Therefore, we can conclude that AEC≅ AED by SSS or Side-Side-Side. That is when all sides of triangles are congruent then both triangles are deemed to be equal.

A 90-inch length of ribbon is to be cut into three pieces. The longest piece is to be 30 inches longer than the shortest piece,

Free_Kalibri [48]

Lets name the shortest piece a, the medium b and the longest c

Together they are 90inches
$a + b + c = 90$
The longest is 30 inches longer than the shortest
$c = a + 30$
The third piece is half the lenght of the longest
$b = \frac{c}{2}$

So if you place c=a+30 in the other 2 equasions you get

$a + b + (a + 30) = 90 = 2a + b + 30$
And
$b = \frac{30 + a}{2}$
Now if you put this 2 toghether u get
$2a + \frac{30 + a}{2} + 30 = 90$
Multyplied by 2
$4a + 30 + a + 60 = 180$
$5a = 90$
Meaning that a=18inches

Now that we have the lenght of a we put it in the previous equasion

$b = \frac{30 + 18}{2}$
So b=48/2 which means b=24inches

And together they must be 90 so

$18 + 24 + c = 90$

C=48inches
