Using supplementary angle theorem

  • <CDE=<ABE

As BD bisects AC

  • AE=EC
  • BE=ED

So ∆AEC\cong∆DEC(SAS)

Also similarly

  • ∆BEC\cong∆AED

Hence it's a parallelogram

Please Helps me i put this for 92 points
natulia [17]

Answer:

Michael is incorrect.

if we take the steps Michael says and move the ABCDE up 8 and right 10, not all of the points line up.

Step by step explanation:

In order to get the shapes to line up, we need to flip (reflect) ABCDE onto the 2nd Quadrant, then we can move (translate) it to the right by 10.

27/8+11/3 please help
a_sh-v [17]

Answer:

The answer is 7 1/24

Step-by-step explanation:

27/8 + 11/3

I multipled 27/8 by 3/3 (needed the 8 to become 24)

I multiplied 11/3 by 8/8 (needed the 3 to become 24)

We get:

81/24 + 88/24

Then you add

169/24

Simplify

7 1/24
