Is there a photo for this problem? I solved what i coulda. givenb. givenc. def. of supplementary angles (i think)d.photo to support this?
e.
$10.50 X 35 would give you your answer which would equal $367.5
Find <em>n</em> :
P = a + b + c
63 = n + (4n - 8) + (2n + 8)
63 = (n + 4n + 2n) + (-8 + 8)
63 = 7n
n = 63 ÷ 7
n = 9
Sides :
1.) n = <u>9</u>
2.) 4n - 8 = 4(9) - 8 = 36 - 8 = <u>2</u><u>8</u>
3.) 2n + 8 = 2(9) + 8 = 18 + 8 = <u>2</u><u>6</u>
