Tolong bantu jawab semuanya dong pake caranya ya...Terima kasih. hehe

1) pd² = 10² - (5+3)²
pd² = 100 - 64
pd² = 36
pd = √36
pd = 6 cm

2) 21² = p² - 20²
p² - 20² = 21²
p² - 400 = 441
p² = 441 + 400
p² = 841
p = √841
p = 29 cm

3) menurutku 1 atau 2

4) 24² = p² - (22-4)²
576 = p² - 324
p² - 324 = 576
p² = 576 + 324
p² = 900
p = √900
p = 30 cm

5)
gd² = j² - (r1+r2)²
atau
gd = √j² - (r1+r2)²

6) 24² = 26² - (15-r2)²
(15-r2)² = 26² - 24²
(15-r2)² = 676 - 576
(15-r2)² = 100
15 - r2 = √100
15 - r2 = 10
-r2 = 10 - 15
-r2 = -5
r2 = 5 cm

7) PQ² = OP² - OQ²
40² = 50² - OQ²
OQ² = 50² - 40²
OQ² = 2500 - 1600
OQ² = 900
OQ = √900
OQ = 30 cm

8) PQ² = OP² - OQ²
PQ² = 25² - 7²
PQ² = 625 - 49
PQ² = 576
PQ = √576
PQ = 24 cm

9) AB² = MN² - (MA-NB)²
AB² = 10² - (4-2)²
AB² = 100 - 4
AB² = 96
AB = √96
AB = √16×6
AB = 4√6 atau 9,79 cm

semoga membantu dan bermanfaat
