WebABCD is a rectangle and diagonals of a rectangle are equal and bisect each other. OA = OD ⇒ ∠ODA = ∠DAO (angles opposte to equal sides are equal) ⇒ ∠ODA = 55° In DODA, by angle sum property, ∠ODA + ∠DAO + ∠AOD = 180° ⇒ 55° + ∠55° + ∠AOD = 180° ⇒ ∠AOD = 70° Solution 10 Solution 11 Solution 12 Solution 13 Correct option: (c) WebMar 11, 2024 · In a rhombus ABCD, m∠A = 31°.

WebCorrect option is B) Using the formula sin90 ∘AB = sin30 ∘OB where O is the centre of rhombus and we know that diagonal of rhombus bisect each other at right angles. AB=6cm OB=OD= two segments of diagonal BD bisected by O. ∠A=60 ∘ ∴∠OAB= 260 ∘=30 ∘ … WebHow does this rhombus calculator work? Depending on the figures you know this rhombus calculator can perform the following calculations: If Angle (A) is given then the other 3 angles will be computed: B = 180° - A C = A D = B The same goes in case Angle (B) is given: A = 180° - B C = A D = B Web1.
