James was trying to sleep one night but there was too much noise around him. His clock ticked every 20
seconds; a tap was dripping every 15 seconds and his
pet dog snored every 27 seconds. He noticed on his
clock that all three events happened together on the
stroke of midnight.
(a) After how many minutes would all the three
events happen together again?
(b) How many times would all three events happen together again between midnight and one o’clock?

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle

Where is the problems
