Answer:

Step-by-step explanation:

In ΔABD and ΔBDC

  BD = BD  {common to both trianles}

 ∠ABD =∠DBC    {BD is bisects ∠B}

∠BAD =   ∠BCD   {given in the sum, both are 90}

ΔABD and ΔBDC are congruent triangles.

7) so, AD conguent CD

8) False.

AB congruent CB because ΔABD and ΔBDC are congruent as CPCT rule.

AB congruent CB not because of BD is bisector of  ∠B

Answer: Look below :)

Step-by-step explanation:

7. <u>AD</u> and <u>CD</u> are congruent.  Each of the triangles are the same in length and shape (both are right triangles). They are the same but are mirrored over the line <u>BD.</u>

8.  I have no idea. Sorry.

Answer---&gt;x/3<br>Process?​
Komok [63]

Step-by-step explanation:

2x/3 - x/3 = x/3

they both have the same denominators (number at the bottom of the fraction) so all you have to do it subtract the numerators (top of the fraction) together. 2x-x =x, that's why it's x on the numerator for the answer

hope this helps

Maurinko [17]
Jack should remove the maximum and minimum weight potatoes from the average weight of the potatoes to compensate for the extremes. Therefore, we are left with a data set of:
8, 9, 11, 7, 7, 8, 9, 7; so n = 8
The sum of these is 66
The average weight of each potato is:
66/8
= 8 ounces
