Ab and c lie on a straight line BD=CD BCD=15 BAD=5 Work out x

Step-by-step explanation:

The attachment completes the question;

From the question, we have the following given parameters

Required

Solve for x

Since then

--- Property: Base angle of an isosceles triangle

Also, ABC is a straight line;

So:

--- angle on a straight line

Substitute 15 for

Make the subject

Considering triangle DBA

---- angles in a triangle

Substitute 165 for and 5 for

Make x the subject

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !
