Answer:

x=60

Step-by-step explanation:

here DOB and AOC are vertically opposite angles and the values of them are equal. so lets take the two angles as y.

x+DOB is 90(because EOA is 90 and the sum of angles in a straight line is 180), DOB is y and can write a equation as x+y=90

and 30+2x+y = 180 ,

2x+y=150, (180-30)

then two equations can be made.

x+y=90

2x+y=150

simplifying these two simultaneous equations

can get x as 60. and 2x is 120.

This is easier to understand with a picture...

We know that a triangle has 3 sides right?

Well, if the perimeter is 39 and there are 3 sides you would divide 39 by the 3 sides

39/3=13

Therefore, one side of the triangle would equal 13
