Two parallel lines are cut by a transversal. One of the two interior angles on the same side of the transversal contains 15[degrees] more than the other. Find the degree measure of the smaller angle....thank you so much!

The interior angles on the same side are supplementary. Let's call them x (smaller angle) and x+15 (larger one), and we know their sum is 180:
x + (x + 15) = 180
2x + 15 = 180
2x = 165
x = 82.5
The larger one is 82.5+15 = 97.5.

the 2 angles add up to 180 degrees
a + (a + 15) = 180
2a + 15 = 180
2a = 165
a = 82.5 degrees

the respond is $60, by way of fact : $1320= 2 diamond and a couple of silver rings ($660+ $660) on the grounds that we want 2 extra silver rings to extra healthful the 1st quota, the the remainder of a million,440- 1320 is the value of two silver rings. Divide that by skill of two and you get 60 money. for this reason a diamond is six hundred, so which you will examine.all of it provides to 1440. i'm in grade 8 too, and on the beginning up that replaced into truly complicated.
