Soalnya ada di foto dibawah pertanyaannya hitunglah a2+b2

Bismillah iya.

Silahkan di cek kembali…

(2+2+3+5+6+a) = 6 x b

18 + a = 6b
→ a = 6b – 18

(2+3+4+5+6+b) = 6 x ( a – 2)

20 + b = 6(6b – 18 – 2)

20 + b = 36b – 120

36b – b = 120+10

35b = 140

b = 140/35

b = 4

a = 6×4 – 18

a = 24 – 18

a = 6

(a² + b²) = ( 6² + 4²) = 36 + 16 = 52
