Question 365967: A.Find all of the values of x for which the measure of an acute angle is between 60 and 105, here is the main equation
(3x+18)* the mark means degrees.
B.From the range found in part A, find all values of x for which the acute angle will be obtuse. I just need equation.

Once the angle is beyond 90, it's no longer acute.
60%3C3x%2B18%3C105
3x%2B18%3E60
3x%3E42
x%3E14

3x%2B18%3C105
3x%3C87
x%3C29

Acute: 3x%2B18%3C90
Right: 3x%2B18=90
Obtuse: 3x%2B18%3E90
