Answer:
Step-by-step explanation:
DE² = 29² - 21² = (29+21)(29-21) = 50*8 = 400
DE =√400 = 20
x = DE {in Kite, diagonal AC bisect DB. DE = EB}
x = 20
DC² = DE² + EC² = 20² + 99 ² = 400 + 9801 = 10201
DC = √10201 = 101
y =101
In Kite, adjacent sides are equal.
AD = AB = 29
CD = CB = 101
Perimeter = 29 + 29 + 101 +101 = 260
the answer is D if it is not then try A
120/360 =
-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29
7-12= -5
7+12= 29
-5 ≤ n ≤ 29 or -5 ≤ n < 30 or -6< n ≤ 29 or -6 < n < 30
either one is acceptable. question was not clear but i did my best! :)
its 34 boy im telling you
