Question

ABCD is a rhombus. If angle a=70
find angle cdb
​

Answer 1

Let ∠CDB = x° Then CD = CB => ∠CBD = x° ∠BCD = ∠BAD = 70° (Opposite angles of rhombus) ∴ x + x + 70° = 180° (sum of angles of ∆ equal to 180°) 2x = 110° x = 55° ⇒ ∠CDB = 55°in-the-given-figure-abcd-is-a-rhombus-if-a-70-then-find-cdb
