Let the person's arm length be = x
Condition is : sleeve lengths available from 20 inches to 40 inches and the length of the sleeves should be about 1.2 times a person's arm length.
So, the inequality equation becomes:

This gives x=
or 
or x=
=33.33 or 
Hence, the shop does not provide tuxedos to people with arm length less than 16.66 inches and greater than 33.33 inches.
The problem here is incomplete, but I found a problem online that must be the same to this. The picture is attached. The figure shown is a stemplot. The numbers to the left of the bar is the stem, while numbers to the right are the leaves. So, if you want to find 10.1%, find the row where the left number is 10. Then, find the corresponding 1 among the numbers to the right. That is 10.1% for the older folks living in Colorado.
A + 3A = 120
4A = 120
A = 30
B = 90
1 . 48 is the answer as the two bottom ones are equal 180-66-66=48
2. 117 degrees as the angle is the same as the other congruent angle shown in the diagram
