The number 10 has exactly four factors 1,2,5 and 10. find the next number after 10 that has exactly four factors.

11 has 2 factors : 1 and 11
12 has 6 factors : 1, 2, 3, 4, 6, and 12
13 has 2 factors : 1 and 13
14 has 4 factors : 1, 2, 7, and 14

So, the answer is 14

Hello!

I believe the next number that has exactly four factors, after 10, is 14.

14 FACTORS: 1, 2, 7, 14.

I hope this helped you! :)

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
