Angle AOB + angle BOC = angle AOC
7x + 30 + 9x + 42 = 104
16x = 104 - 72
16x = 32
x = 2 degrees
Angle BOC = 9x + 42 = 18 + 42 = 60 degrees

Answer:
x = 10 cm
Step-by-step explanation:
(3x + 2) + (3x + 2) + (4x - 5) + (4x - 5) = 134 cm
combine like terms:
14x - 6 = 134
add 6 to each side of the equation:
14x = 140
divide both sides by 14:
x = 10
