9514 1404 393

  x = 63

Step-by-step explanation:

The base angles of each isosceles triangle are equal, so we can write the sum of the four angles in the quadrilateral as ...

  72° +(72° +x°) +x° +90° = 360° . . . . . clockwise from upper left

  2x = 126 . . . . . . . . . divide by °, subtract 234

  x = 63 . . . . . . . . . . . divide by 2

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
