Question

in a cyclic quadrilateral ⬛ ABCD if m angle A=65 then m=D=?​

Answer 1

SOLUTION

CORRECT QUESTION

In a cyclic quadrilateral ABCD if ∠A = 65° then ∠D = ?

CONCEPT TO BE IMPLEMENTED

In a cyclic quadrilateral sum of opposite angles = 180°

EVALUATION

Here it is given that ABCD is a cyclic quadrilateral

Now ∠A = 65°

We know that in a cyclic quadrilateral sum of opposite angles = 180°

∴ ∠A + ∠D = 180°

⇒ 65° + ∠D = 180°

⇒ ∠D = 180° - 65°

⇒ ∠D = 115°

FINAL ANSWER

∠D = 115°
