Let other 2 angles be d
44 + 2d = 180°
(sum of triangle)
2d = 180 -44
2d = 136
d = 136/2
d = 68
x = 68 + 44 (exterior angle is equal to sum of interior opposite angles)
x = 112°
l
2. part
let the other angles be d
3d = 180° (sum of angles of triangle)
d = 60°
x = 60 + 60
x = 120°

Okay, Chemistry runs every 10 minutes and the Recycling runs every 6 minutes. In order to find what time they both start at the same time you must find the lowest common multiple (if you are using mathematical terminology). To do this the long but visual way you can write out each of the times and find the first ones that are the same.
Chemistry: 10:00 10:10 10:20 10:30
Recycling: 10:00 10:06 10:12 10:18 10:24 10:30
As you can see both Chemistry and Recycling both have a LCM of 10:30 which tells us that the time for which both Chemistry and Recycling start at the same time during the show is 10:30AM.
According to my test it is 9 so it should be right
