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
30
If you plug in 5 for x and 3 for y then the equation would be 3(5)+5(3) or 15+15.
the area sector is 123.2
