Jawab ya Tolong banget plis bantu

19.LuasJuringOPQ=105/75x15
=21cm²
20.LuasJuring=90/360x22/7x14x14
=154cm²
Luas segitiga=axt/2
=14x14/2
=98cm²
Luasarsir=154-98=56cm²

16. KL = 34.
KM = 30.
LM = [tex] \sqrt{34 ^{2} - 30 ^{2} } = \sqrt{1156-900} = 16[/tex]
.
18. ∠ABD = [tex] \frac{1}{2} [/tex] x ∠COD.
[tex] \frac{1}{2} [/tex] x 96 = 48.
.
19. [tex] \frac{Luas Juring OPQ}{Luas Juring ORS} = \frac{105}{75} [/tex]
[tex] \frac{Luas Juring OPQ}{15} = \frac{105}{75} [/tex]
Kali silang, menjadi
Luas Juring OPQ = [tex] \frac{105}{15} [/tex] x 15
Luas Juring OPQ = 105 : 5 = 21 cm
.
20. Luas Tembereng = Luas Juring - Luas segitiga
LT = [tex] \frac{90}{360} [/tex] x [tex] \frac{22}{7} [/tex] x 14 x 14 - [tex] \frac{1}{2} [/tex] x 14 x 14 = 154 - 98 = 56 cm
