Question

9. In parallelogram ABCD,
<C=67.5degree. Then <A:<B=​

Answer 1

Answer:

Step-by-step explanation:

In parallelogram opp angles are equal and sum of all angles is 360 so,

<c = <a and <d = <b

<a = 67.5

<a + <b + <c + <d = 360

67.5 + 67.5 + <b + <d = 360

135 + 2<b = 360

[hence angle b is equal to angle d]

<b = 112.5
