The larger triangle ABC is similar to the smaller triangles as follows.
Triangle ABC ~ triangle DBA by AA similarity because they share angle B and angles A and D are right angles.
Triangle ABC ~ triangle DAC by AA similarity because they share angle C and angles A and D are right angles.
So you can set up the following proportions, seeing that the answers are involving either AC^2 or AB^2.
AB/BD = BC/AB When you cross multiply, you get AB^2 = BC times BD, which is the first answer listed.
Using the other proportion, AC/CD = BC/AC, when you cross multiply, you get AC^2 = BC times CD, which is not one of the answers listed.

Step-by-step explanation:
The numbers are ordered from greatest to least.
The numbers are: 582, 478, ?, 326, 201.
The missing number is between 478 and 326.
Therefore all the following are possible solutions.
400
420
330
458
In fact any number greater than 326 but less than 478 is correct

Step-by-step explanation:
m^4 + 1/ m^4
m-1/m = 3
m - 1 = 3m
m = -1/2
-1/2^4+ 1/ -1/2^4
1/16+1 / 1/16
(17/16 )/(1/16)
