tolong jwb pakek jalan dri no 1-10

1. teorema phythagoras
sisi miring² = alas² + sisi tegak²
a² = c² + b²

2. teorema phythagoras
PR² = PQ² + QR²
5² = 4² + QR²
25 = 16 + QR²
9 = QR²
QR = √9 = 3

3. teorema phythagoras
30² = 18² + x²
900 - 324 = x²
x = √576 = 24

4. d1 = 36, maka 1/2 d1 = 18, dan d2 = 48 maka 1/2 d2 = 24
teorema phythagoras
x² = 18² + 24² = 324 + 576 = 900
x = √900 = 30

6. x² = 24² + 7² = 576 + 49 = 625
x = √625 = 25

7. x² = 169, maka x = 13

10. diagonal persegi = r√2 = 20√2 = √400 x √2 = √800
