Question

Tolong bantuin jawab dong pliisssssss

Answer 1

1. a. km = nm+kn, nm = 4 = √a1xa2 = 16 = 2 x a2, a2 = 8, nm = 8, km=10
b. 2√5 ² = 2²+ln² (phytagoras) = 20 = 4+ln², ln²=16, ln = 4
c. 100-20 = 80 = √80
2. jawabannya 3
3. pake perbandingan : 16/8 = 2, 2 x 4 = 8cm
4. Kan itu sama jadi tinggal disamakan aja : pake perbandingan
15/3 = 5 x 5 = 25 , X=25
maaf klo salah

Answer 2

Cba jawab ya

1) KL² = KN x KM
(2√5)² = 2 x (2 + NM)
20 = 4 + 2NM
16 = 2NM
NM = 8 cm

LN² = KN x NM
LN² = 2√5 x 8
LN = √(16√5)
= 4√√5 cm

LM² = KM² - KL²
= 100 - 20
= 80
LM = √80 = 4√5 cm

2) Pakai rumus ikan
5,4 = (2 x 15 + 8 x t)/(2 + 8)
5,4 = (30 + 8t)/10
54 = 30 + 8t
24 = 8t
t = 3

4) x/5 = 15/3
x/5 = 5
x = 25
