Question

If BD bisects
ABC, ABD = 2x + 3, and
DBC = 3x - 13, find ABD.

Answer 1

35

Explanation:

Since its an angle bisector, both angles would be equal to each other.

3x-13=2x+3

Now you need to get x alone.

Subtract 2x from each side.

x-13=3

Still need x alone so add 13 to each side (since it negative addition)

x=16

You have x, but you need ABD

Plug 16 in for x

2(16)+3

32+3

35
