Upper primary school mathematics question UPQ72

 

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

Solution:

               ∠ x = 180⁰  – 110⁰ = 70⁰ (parallel lines)

               ∠ y = 70⁰ – 36⁰ = 34⁰ (triangle)

               ∠ z = 70⁰ – 35⁰ = 35⁰ (triangle)

                ∠ x + ∠ y + ∠ z = 70⁰ + 34⁰ + 35⁰ = 139⁰
