Answer 2

y = 90°

Step-by-step explanation:

GIVEN

CE = ED

D = 28°

B = 62°

___________________________

TO FIND

y

___________________________

We know that,

CE = ED

So,

C₁ = D

D = 28°

C₁ = 28°

___________________________

We know that,

Opposite angles are equal

So,

C₁ = C₂

C₁ = 28°

C₂ = 28°

___________________________

We know that,

Addition of all angles of a triangle is 180°

A + B + C₂ = 180°

A + 62 + 28 = 180°

A + 90 = 180°

A = 180 - 90

A = 90

A = 90°

___________________________

We know that,

Addition of linear pair is 180°

A + y = 180° ( Linear Pair )

90 + y = 180°

y = 180 - 90

y = 90

y = 90°
