Jawaban:
10.
(5/3 m)² = 16² + m²
25/9 m² = 256 + m²
16/9 m² = 256
m² = 144
m = 12
11.
jarak² = (13-10)²+(16-20)²
= 9+16
jarak = √25
= 5
12.
AC² = AB² + BC²
= 6²+6²
= 72
AC = √72
= 6√2

= (13-10)²+(16-20)² =
= 3² + 4²
= 9 + 16
= 25
= √25
= 5

AC² = AB²+ BC²
= 6²+6²
= 6 × 6 + 6 × 6
= 36 + 36
= 72
= √72
= 6-√2
