Question

in ABC B=45 degree, c=55 degree and bisector of angle a meet BC at. D find ADB and a dc

Answer 1

Angle ADB equals 95
There will be two triangles and sum 
All angle are 180then 45+55+a equal180 
The angleA equal80 as it is bisecting then each 40 
When the d meets two triangles will be formed 

For each one two angles are given find the 3rd ond

Hope This Helps :)

Answer 2

angle adb equal 95
there willbe two triange and sum
all angle are 180then 45+55+a=180
100+a=180
a=180-100
a=80
