Question

ABCD is a rhombus in which AC and BD are diagonals intersecting at O. if angle OAB =55 find angle CDO


HEY GUYS PLEASE GIVE ME THE CORRECT ANSWER IVE GOT MY MATHS EXAM TOMORROW AND FOR FFS IF U DON'T KNOW THE ANSWER THEN PLEASE DONT SPAM.​

Answer 1

35°

we know that

$\bf \angle$ OAB is intersected into two parts

Hence, $\bf \angle$ DAB will be 55° × 2 = 110°

• Let's assume that $\bf \angle$ CDO = x

According to the question,

$\bf \angle$DAB + $\bf \angle$ CDA = 180° ( adjacent angles are equal to 180° )

$\bf \to$ 2x + 110° = 180°

$\bf \to$ x = 35° ans.

Answer 2

Answer:

x=35° is right answer
