If a factory can produce 211 bicycles in 1 month how many can they produce in 1 year

Well if they produce 211 bicycles in a month, to find how many they produce in a year, you gotta multiply by 365. Where did I get 365 from? A year has 365 days. However, 211 times by 365 is 77015. We can then conclude that the factory sells 77015 bicycles in a year.

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
