Question

Find the values of
of the unknones x
only in
following diagrams​

Answer 1

Answer:

interior angles = external angles

50°+60°=x

110°=x

supplementary angles=180°

therefore,x+y=180°

x+110°=180°

x=180°-110°=70°

Therefore,x=70°,y=11

opposite angles are equal

x=60°

In triangle x°+y°+30°=180°

60°+y°+30°=180°

90°+y°=180°

y°=180°-90°=90°

Therefore, x=60°,y=90°
