The sum of three interior angles of a triangle is 180degrees. suppose one angle is 90degrees and the remaining two angles are the same measure. find the measures of the angles algebraically. let one of the unknown angle measures be x. write an equation that can be used to solve this problem.

Tom is the deli manager at a grocery store. he needs to schedule employee to staff the deli department for no more that 260 person-hours per week. tom has one part-time employee who works 20 person-hours per week. each full-time employee works 40 person-hours per week. write and inequality to determine n, the number of full-time employees tom may schedule, so that his employees work on more than 260 person-hours per week. graph the solution set to this inequality.
