So lets ABCD are the sides of the square and AB=CD, AC=BD and the Angle ABC = 90 so therefore by making a diagonal we can use the SAS or SSS congruency for two triangles, so we can prove two triangles are equal and that is why the shape is square.
The number of half-hour sittings needed to watch all the shows by Devon is 11
<u>Solution:</u>
Given, Devon records 4 hours of reality shows on her DVR
she records comedy shows for 3/8 of that amount of time.

Devon watches all the reality and comedy shows in half-hour sittings.
We have to find the number of half-hour sittings needed to watch all the shows
Now, number of half hour sittings is given as


Hence Devon needs 11 sittings
1/3 + 5 + 1/2 = total money he had originally
to add fraction we should first find a common denominator for every term.
1/3 + 10/2 + 1/2 = total
1/3 + 11/2 = total
2/6 + 33/6 = total
35/6 = total
