Verified answer

Jawaban:

a. 90°

b. 60°

Penjelasan dengan langkah-langkah:

a. QRP = QRO + PRO

QRO = 180 - (180 - (2 × PQR)) - PQR

QRO = 180 - (180 - (2 × 30)) - 30

QRO = 180 - (180 - 60) - 30

QRO = 180 - 120 - 30

QRO = 30°

..

PRO = (180 - POR)/2

PRO = 180 - 60)/2

PRO = 120/2

PRO = 60°

..

QRP = QRO + PRO

QRP = 30 + 60

QRP = 90°

..

b. QPR = PRO

QPR = 60°
