Question

kuis harus pakai cara biar paham gue ​

Answer 1

Jawaban:

1. B

2. A

13² = KL + 12²

KL = 13² - 12²

= 169 - 144

=

= 5 cm

Luas segitiga = ½ × alas × tinggi

= ½ × 12 × 5

= 6 × 5

= 30 cm²

3. B

9² + 6² = 10²

81 + 36 = 100

117 > 100

Lancip = t² + a² > sisi miring²

4. A

9² + 14² = 17²

81 + 196 = 289

277 < 289

Tumpul = t² + a² < sisi miring²

5. C

8² + 15² = 17²

64 + 225 = 289

289 = 289

Siku-siku = t² + a² = sisi miring²

6. D

= √(( x² - x¹ )² + ( y² - y¹ )²)

= √(( 10 - 4 )² + ( 5 - (-3 ))²)

= √( 6² + 8² )

= √( 36 + 64 )

= √100

= 10
