Question

Find the value of unknown x in each of the following diagrams: ​

Answer 1

Answer:

∠x=50°

Step-by-step explanation:

As we can see that ∠z+120°= 180° [∵Linear pair].

                                 ∠z= 180°-120°

                                   ∠z=60°

In Δ ∠y+110°=180°

       ∠y=180°-110°

       ∠y=70°

∠x+∠y+∠z=180° [∵ Angle sum property]

∠x+70°+60°=180°

∠x+130°=180°

∠x=180°-130°

∠x=50°.
