Answer» Given : A circle m arc(PQ) = 4x - 2 m arc(QR) = 7x - 18 m arc(PR) = 6x + 6 To Find : m arc(QR) = 136° Solution: Full circle 360° m arc(QR) + m arc(PQ) + m arc ( PR) = 360° => 7x - 18 + 4x - 2 + 6x + 6 = 360° => 17x - 14 = 360° => 17x = 374° => x = 22 m arc(QR) = 7x - 18 Substitute x = 22 => m arc(QR) = 7(22) - 18 => m arc(QR) = 154 - 18 => m arc(QR) = 136° m arc(QR) = 136° Learn more: In a circle if two chords are congruent then their CORRESPONDING ...
