Answer 1

Verified answer

A)
AC² = AB² + BC²
(√244)² = (5x)² + (6x)²
244 = 25x² + 36x²
244 = 61x²
61x² = 244
x² = 244 : 61
x² = 4
x = √4
x = 2

maka nilai x = 2

b)
AB = 5x cm
      = 5(2) cm
      = 10 cm

c)
BC = 6x cm
      = 6(2) cm
      = 12 cm

d)
Keliling = AB + BC + AC
             = 10 cm + 12 cm + √244 cm
             = (22 + √244) cm ≈ 37,62 cm
