Sagot :
if you add everything up then
14x-2=180
14x=182
x= 13
So the angles would equal
2(13)+1= 27
3(13)-3= 36
9(13)= 117
The angles are 27 36 and 117
Which makes the smallest angle 27 which is B.
14x-2=180
14x=182
x= 13
So the angles would equal
2(13)+1= 27
3(13)-3= 36
9(13)= 117
The angles are 27 36 and 117
Which makes the smallest angle 27 which is B.
You first have to know that the measure of the three angles of a triangle= 180
add the terms and equal them to 180
2x+1 + 3x-3 =9x= 180
14x-2 = 180
14x= 182
x=13 This is not what you are looking for, you need to
substitute 13 in the original measures
2 (13) +1= 27 degrees
3(13) -3= 36 degrees
9 (13) = 117 degrees
therefore the smallest angle is 27 degrees
if you add all three angle measure it will = 180 degrees
