Question

WILL GIVE BRAINLIEST PLEASE HELP: In rectangle ABCD the diagonals intersect each other at point O and m ABD = 30 degrees. Find BC if AC = 16 in.

Answer 1

Answer:

AngleCOD=angle AOB=62°

As AO=OC=BO=OD

In triangle OCD, OC=OD

Hence angle ODC=(180–62) /2( sum of angle of triangle is 180°)

=118/2 =59°

Step-by-step explanation:

Answer 2

Answer:

8

Step-by-step explanation:

We know that ABD is 30 degrees. To find BC, we need to use sin.

Equation:

BC = 16*sin(30 degrees) I recommend using a calculator to find the sine if you don't know what it means and how to use it. Sine is basically the side length opposite of the angle over the hypotenuse of the right triangle.

BC = 16*0.5

BC = 8

Hope this helps!
