Segitiga
t = √h² - a²
t = √17² - 15²
t = √289 - 225
t = √64
t = 8 cm
Luas segitiga
= 1/2 x a x t
= 1/2 x 15 cm x 8 cm
= 15 cm x 4 cm
= 60 cm²
A²+B²=C².
Karena A=15 dan C=17 maka
15²+B²=17²
B²=17²/15²
B²=289/225
B²=64
B=√64
B=8
Jika B atau tinggi = 8 dan alas = 15 maka luas segitiga adalah 1/2 *15*8=60cm²
