in a triangular flowerbed the smallest angle is 6 degrees less than the next larger angle, whch is 30 degrees less than the larger angle. the sum equals 180 degrees

use algebra.. to let u get started, let the smallest angle be x
so the next larger angle is x + ???, and the largest angle is x + ???
i bet u r smart enough to figure out the rest

s = smallest angle
m = middle angle
l = largest angle
s = m - 6
m = l - 30
s + m + l = 180
therefore s = l - 30 - 6
substituting l for s and m you get
l - 36 + l - 30 + l = 180
add 36 and 30 to both sides you get l + l + l = 180 + 36 + 30
or
3l = 246
divide by 3 on both sides and l = 82
m = l - 30 = 82 - 30 = 52
s = m - 6 = 52 - 6 = 46
s + m = l = 46 + 52 +82 = 180

This problem gives you two expressions for the middle angle, so you have to adjust it a bit for the largest one.
Smallest = x - 6
Middle = x
Largest = x + 30
The sum of the angles is 180. I'm sure you can finish from here.
Sammy, I noticed that you posted 3 even-numbered problems from the same page. Are you trying to get people here to do your assignment for you? You'll eventually have a test where you have to do the work yourself.

very clever Sammy. The odd numberd problems have answers in the back of the book, the even numbered problems can be answered in this forum. I hope your calculator has e-mail capabilities, otherwise you gunna flunk da tess, dude!
