Answer 1

Verified answer

Jawaban:

C. 210 mm

Penjelasan dengan langkah-langkah:

Diketahui :

PR = 29 cm = 290 mm

QR = 20 cm = 200 mm

Ditanya :

PQ = ?

Jawab :

[tex]pq \: = \: \sqrt{pr^{2} \: - qr^{2} } \\ = \sqrt{290^{2} - 200^{2} } \\ = \sqrt{84100 - 40000 } \\ = \sqrt{44100} = 210 \: mm[/tex]

Answer 2

Penjelasan dengan langkah-langkah:

RQ = 20 cm

PR = 29 cm

[tex]\tt PQ^2=PR^2-RQ^2\\\\PQ^2=29^2-20^2\\\\PQ^2=841-400\\\\PQ=21^2\\\\PQ=21~cm\\\\PQ=21\times 10\\\\PQ=210~mm~(C)[/tex]
