Answer:
a,b
Step-by-step explanation:
In a kite, all of the angles added together equal 360. You already know there are two right angles, and because of this, you would subtract 180 from the 360, leaving you with 180. In order to solve for x, you have to add 18x-2 to 12x+2 and set it equal to 180. Your equation would be 18x - 2 + 12x + 2 = 180. The 2's would cancel out, leaving you with 18x + 12x = 180, 30x = 180, then 6 = x.
5n + 13.....n = -5
5(-5) + 13 =
-25 + 13 =
-12
4n + 8.....n = -5 <===
4(-5) + 8 =
-20 + 8 =
-12
15 = 2w - 5
15 + 5 = 2w
20 = 2w
20/2 = 2w/2
10 = w
w = 10
