Thanks for helping, I really appreciate it

a)ΔFHA is similar to ΔZIA by hypotenuse side test.

reason:- angle H and angle I are of 90 degrees.

b) FH/ ZI = HA/ IA = FA/ ZA

angle F = angle Z, angle H = angle I , angle angle A = angle A

The scale factor is 3/2( HA/IA = 12/8 = 3/2)

c) IZ = 3.3 ( FH/ IZ = 3/2, 5/ IZ = 3/2, IZ = 10/3 = 3.33)

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
