tolong lgi dong d kerjakan no. 6 smpai 8

6)
P² = 34² - (10+6)²
P² = 1156 - 16²
P² = 1156 - 256
P² = 900
P = √900
P = 30 cm

7)
24² = p² - (13+3)²
576 = p² - 16²
576 = p² - 256
p² - 256 = 576
p² = 576 + 256
p² = 832
p = √832
p = 28,84 cm

8)
20² = 25² - (12-r)²
400 = 625 - (12-r)²
(12-r)² = 625 - 400
(12-r)² = 225
12 - r = √225
12 - r = 15
-r = 15 - 12
-r = 3
r = -3 cm

maaf kalo kurang tepat
semoga membantu dan bermanfaat
