Question

In the given figure, AD divides ZBAC in the ratio 1: 3 and AD = DB.
Determine the value of x.​

Answer 1

Step-by-step explanation:

angle BAC is divided into ratio 1:3

let angle BAC is divided as 1x:3x

therefore angle BAC =1x+3x=4x

BAC+EAC=180° (LP)

4x+108°=180

4x=180-108

4x=72

x=18
