Question

Diagonals of rectangle ABCD intersect at point O. If AC = 18 cm then find BO and
if ∠ CAD = 350 then find ∠ ACB.
​

Answer 1

Answer:

The value of BO is 9cm

angle ACB is 350°

Answer 2

Diagonals of a rectangle are congruent.

So, AC=BD=8 cm

Also, rectangle is a parallelogram so, the diagonals bisect each other.

Thus, BO=OD=4 cm

Now, AD∣∣CB

So, ∠CAD=∠ACB=35⁰

(Since, alternate interior angles are equal)
