The answer should be 17 because if the triangles are congruent, angle RTS would be equal to angle YZX. So, 2x+24=4x-10
Subtract 2x from both sides to get the variable on one side
24= 2x-10
Then you can add 10 to both sides
34= 2x
Divide by 2
x=17
Assuming you are asking how many weeks, than the answer would be 17-32, because at 16 weeks the growth would be 4 cm, totaling at 11, but you need more than 11cm, and at 32 weeks it's at 15 cm.
Answer:
These are similar. The scale factor is 1.5 going from ABC to DEF.
Step-by-step explanation:
What I did was divide the side lengths of DEF by the corresponding side on ABC.
12/8 = 1.5
9/6 = 1.5
15/10 = 1.5
Since the scale factor is the same on all three sides, these two figures are similar.
