Supplementary means they equal 180 when added. Therefore:
X+56+3x=180
Combine common units
4x+56=180
Subtract 56 from both sides
4x=124
Divide by 4
X=31
Now we know the smaller angle is 31 degrees. Now we plug that into the larger angle:
3(31)+56
93+56
149
The larger angle is 149 degrees.
I hope this Helps!

The percentage of change: This is how you set it up
% change = (New old value) =
(Old value) = x 100 %
40 is the old value and 72 is is the new value
The new value is greater than the old value.
(72 - 40) /40)x 100 = 80 or 80%
the percent change from 40 to 72 represents a positive change (increases) of 80.
