8x + 3× + 9x = 180
20x = 180
x = 180/20
x = 9
The smallest angle is: 3×9 = 27 degrees
Note: 180 degrees is the sum of angles in a triangle
Answer:
15>x*3
i don't know what you tried to say but this is what I think the answer is.
The answer to your question is : C. 30
You subtract 72 and 42
72-42=30
if a whole number, put the number above a one like so : if the number was 8, write it as 8/1
multiply the number by the reciprocal of the fraction
example: 8 divided by 1/3
8/1 times 3/1 =24/1
=24
