nilai x pada gambar di atas adalah....cm tolong dong solarnya bsok di kumpulin

Mapel Matematika
Bab Teorema Phytagoras

Sisi Miring^2 = Tinggi^2 + Alas^2
(✓360)^2 = (2x)^2 + x^2
360 = 4x^2 + x^2
360 = 5x^2
72 = x^2
x = 6✓2 cm

Penyelesaian :
Sisi miring
[tex] {( \sqrt{360} )}^{2} = {(2y)}^{2} + {y}^{2} \\ 36 0 = {4y}^{2} + {y}^{2} \\ 360 = {5y}^{2} \\ 72 = {y}^{2} \\ y = \sqrt{72} \\ y = \sqrt{36 \times 2} \\ y = 6 \sqrt{2} \: cm[/tex]

Maaf kalau salah ^_^
