Step-by-step explanation:
Suppose the triangles are similar:
The side lenghts would be proportional as follows
XZ/DF = XY/DE
12/8 = 9/x cross multiply expressions
12x = 72 divide both sides by 12
x = 6
Answer:
sq root of 64 = 8, sq root of 81 = 9, 8 and 9
Step-by-step explanation:
Since Sq root of 64 = 8 and Sq root of 81 = 9 it is known that sq root of 66 is between 8 and 9

Answer:
There are 1,037,158,320 ways to choose a committee of 18 among 33 students.
There are 4,939,200 ways to choose 5 freshmen from 7, 6 sophomores from 8, 4 juniors from 8, and 3 seniors from 10.
Step-by-step explanation:
33!/18!15! = 1,037,158,320
7!/5!2! * 8!/6!2! * 8!/4!4! * 10!/7!3!
= 7*3 * 7*4 * 7*5*2 * 10*4*3 = 4,939,200
