Question

0.7 Find the value of x and y in the given triangle.​

Answer 1

Answer:

x=70°

y=70°

Step-by-step explanation:

40°+ y = 110° [Exterior angle property]

y = 110°- 40°

y = 70°

Now,

x+y+40° = 180° [Angle sum property]

x+ 70° + 40°=180°

x+110°=180°

x=180°-110°

x=70°

Answer 2

Answer:

x = 70°

y = 70°

Step-by-step explanation:

x + 110° = 180°

x = 180° - 110°

x = 70°

Now,

y + 40° + x = 180°

y + 40° + 70° = 180°

y + 110° = 180°

y = 180° - 110°

y = 70°
