Question

The measure of an acute angle is less than 90 degrees. If an acute angle measures 3x - 15, then the inequality to represent its measure is 3x - 15 < 90. Solve to find the measure of x.




x < 35

x < 45

Answer 1

You treat inequalities similar to an equal sign. The only thing that changes is when you divide or multiply by a negative number. Then you have to change the inequality around.

Answer 2

is it X<35

Answer 3

You should be able to figure this out. Very simple algebra problem.
