Thanks for helping, I really appreciate it

Answer:

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)

A triangle has a perimeter of 77 centimeters and one side is 25 centimeters. The other
Vitek1552 [10]

Answer:

  36 cm

Step-by-step explanation:

Let x represent the multiplier of the ratio units. Then the perimeter is the sum of the side lengths:

  77 = 25 + 4x +9x

  52 = 13x . . . . . . . . subtract 25

  x = 4 . . . . . . . . . divide by 13

  4x = 4(4) = 16 . . . . find the other side lengths

  9x = 9(4) = 36

The side lengths are 25 cm, 16 cm, 36 cm. The longest side is 36 cm.
