Question

9. ABCD is a rhombus such that ZACB = 40°. then ZADB =
(a) 45°
(b) 50°
(c) 40°
(d) 60​

Answer 1

Angle ADB is 45 *

Because angle ACB is 45* so this angle is also 45*

Answer 2

Answer:

50°

Step-by-step explanation:

let the mid point be o

so, angle BOC is 90°

so,angle OBC will be 50°. ( sum of interior angles of triangle is 180°)

so,angle OBC = angle ADB

so,angle ADB is 50°
