Hey there!
Here's your answer: m<2=114.52 degrees
Here's how I got it: we know that a linear pair of angles is supplementary, aka the sum of the angles is 180 degrees.
you would add 18x-1 and 23x+7 together to equal 180 and solve for x.
then, you would substitute x for 4.24 (rounded) into 23x+17
23(4.24)+17=114.52
Hope this helps!
