Can someone me with this math question

2/3

Step-by-step explanation:

These two figures are similar since they have the same shape but not the same size

Yellow figure is larger than the orange figure therefore, the yellow figure is a larger or a dilated version of the orange figure.

Scale factor = Small side

                       Large side

Scale factor = 10/15

Scale factor = 2/3

The scale factor of this dilation is 2/3. The orange figure is dilated 2/3 times to form the yellow figure.

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
