Question

Ini 10.70, diagonal AC of rectangle ABCD makes an angle of 35 with side BC. The
measure of acute angle COD between the diagonals is
(A) 45
(B) 35°
(C) 70°
(D) 55°​

Answer 1

Answer:

55°

Step-by-step explanation:

Firstly check diagram given in attachment

Given :

$\angle \: acb = 35 \degree \\ \\ \angle \: abc = 90 \degree \\ \\ \angle \: bac = x$

We know that sum of angles in a triangle = 180°

$35 + 90 + x = 180 \\ \\ 125 + x = 180 \\ \\ x = 180 - 125 \\ \\ x = 55$
