Question

perhatikan gambar!!
panjang sudut AC adalah??
pakai caranya ya kak​

Answer 1

Jawaban:

Penyelesaian :

• BC = 25 cm
• AB = 15 cm

[tex] \sf {AC}^{2} = {BC}^{2} - { AB}^{2} [/tex]

[tex]\sf {AC}^{2} = {25}^{2} - {15}^{2} [/tex]

[tex]\sf {AC}^{2} = 625 - 225[/tex]

[tex]\sf {AC}^{2} = 400[/tex]

[tex]\sf AC = \sqrt{400} [/tex]

[tex]\sf AC = 20 \: cm[/tex]

Answer 2

Materi: Teorema Pythagoras

AC² = BC² - AB²

AC² = 25² - 15²

AC² = (25 × 25) - (15 × 15)

AC² = 625 - 225

AC² = 400

AC = √400

AC = 20 cm
