Answer:

x=39

Step-by-step explanation:

It is a four sided thing so the sum of all angles is 360

hence

2x + 3x - 15 + 2x + 2x + 24 = 360

and

x will be 39

3x - 15 = 2x + 24
x - 15 = 24
x = 39

(2x + 24) + 2x = 180
4x + 24 = 180
4x = 156
x = 39

2x + (3x - 15) = 180
5x - 15 = 180
5x = 195
x = 39
