Your question is incomplete.
If you want me to tell the ratio, its 3:2
I would say 3 because terms are separated by a plus or minus sign and there are 2 subtraction signs separating 3 expressions.
If it is area you're looking for, the answer is 7.92 cm^2, or ~7 11/12 cm^2.
Make a bar graph about the length of letters in an animal's name
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!
