Question

please help me its a urgent question​

Answer 1

Answer:

Step-by-step explanation:

ANGLE (A + B + BCA) = 180        [ANGLE SUM PROPERTY]

=> ANGLE BCA = 180 - (45 + 55) = 80

Y = ANGLE B                              [AB II CE, SO, ALTERNATE INTERIOR ANGLES]

=> Y = 55

X + Y + BCA = 180                       [AD IS A STRAIGHT LINE]

=> X = 180 - (55 + 55) = 70

Answer 2

Answer:

x=45⁰

y=55⁰

Step-by-step explanation:

As ,AB II CE

Angle ABC=AngleBCE

(by alternate interior angle)

AngleBCE=55⁰

Angle BCO=Angle A + Angle B

(by exterior angle property)

y+x=45⁰+55⁰

55⁰+x=100⁰

x=45⁰
