Question

in the given figure ab ll cd find the unknown angles x and y

Answer 1

Answer:

x = y = 70°

Step-by-step explanation:

since AE is a straight line :

we can write:

x + 30° + 80° = 180°

x = 180° - 110°

x = 70°

In triangle ABC:

x + y + 40° = 180°

y = 180° - 40° - 70°

y = 70°

Answer 2

Answer:

x = 70 , y = 70

There is a 80 and 30 in the picture and x is also there.

If we see correctly , it will be a 180° line.

80 + 30 + x = 180

110 + x = 180

x = 180 - 110

x = 70

If we add all the angles of the inside of the triangle , we get 180°.

Now we know x. We should find y.

There is 40° inside and we know x as 70°.

40 + 70 + y = 180

110 + y = 180

y = 180 - 110

y = 70
