Step-by-step explanation:
The question has unclear information.
So, I'll answer from scratch
Given
ABC = Right angled triangle
DB bisects ABC
Required
Prove that CBD = 45
From the question, we have that:
ABC is right angled at B
So, when DB bisects ABC, it means that DB divides ABC into two equal angles.
i.e.
![CBD = ABD](https://tex.z-dn.net/?f=CBD%20%3D%20ABD)
and
![CBD + ABD = 90](https://tex.z-dn.net/?f=CBD%20%2B%20ABD%20%3D%2090)
Substitute CBD for ABD in ![CBD + ABD = 90](https://tex.z-dn.net/?f=CBD%20%2B%20ABD%20%3D%2090)
![CBD + CBD = 90](https://tex.z-dn.net/?f=CBD%20%2B%20CBD%20%3D%2090)
![2CBD = 90](https://tex.z-dn.net/?f=2CBD%20%3D%2090)
Divide both sides by 2
![\frac{2CBD}{2} = \frac{90}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2CBD%7D%7B2%7D%20%3D%20%5Cfrac%7B90%7D%7B2%7D)
![CBD = \frac{90}{2}](https://tex.z-dn.net/?f=CBD%20%3D%20%5Cfrac%7B90%7D%7B2%7D)
![CBD = 45](https://tex.z-dn.net/?f=CBD%20%3D%2045)
Hence, it is proved that ![CBD = 45](https://tex.z-dn.net/?f=CBD%20%3D%2045)
