Upper primary school mathematics question UPQ72

In the figure, what is the value of ∠ x + ∠ y + ∠ z ?

*Solution:*

∠ x = 180^{0 } – 110^{0} = 70^{0} (parallel lines)

∠ y = 70^{0} – 36^{0} = 34^{0} (triangle)

∠ z = 70^{0} – 35^{0} = 35^{0} (triangle)

∠ x + ∠ y + ∠ z = 70^{0} + 34^{0} + 35^{0} = 139^{0}
