What is the measure of angle CBD ?

What is the measure of angle CBD ?

ADB=50+65+65=180

angle bisector -> angle on a line 180 degrees. 180-65=115

x= 180-115=65, 65/2=32.5

CBD=32.5+115+32.5

x=32.5

Actually, I asked aboutADB=50+65+65=180

angle bisector -> angle on a line 180 degrees. 180-65=115

x= 180-115=65, 65/2=32.5

CBD=32.5+115+32.5

x=32.5

Maybe, that's what you mean by

" angle bisector -> angle on a line 180 degrees. 180-65=115 ",

but an angle bisector cuts an angle exactly into two angle of equal measure.So, yes, .∠ CBD = 180° - 65° = 115° .

It's really very confusing, and incorrect, when you state the following.

CBD=32.5+115+32.5
