left side triangle is a 5,4,3 or right angled triangle. so angle b/w side 4 and 3 is 90. therefore corresponding angle in quad is 90.
right side triangle is an equilateral. so angle b/w sides 1 and 1 is 60. therefore corresponding angle in quad is 60.
therefore in quad
90 + 60 + x + x = 360
2x + 150 = 360
2x = 210
x = 210/2
x=105
