Consider kite FGHJ. Kite F G H J is shown. Angle F and H are congruent. The length of side F G is 30 centimeters, the length of side G H is (2 a minus 4) centimeters, the length of H J is 24 centimeters, and the length of F J is (3 b + 6) centimeters. What are the values of a and b? a = 14, b = 6 a = 14, b = 8 a = 17, b = 6 a = 17, b = 8

  a = 17, b = 6

Step-by-step explanation:

Sides GF and GH are congruent, so we have ...

  GF = GH

  30 = 2a -4 . . . . substitute given values

  15 = a -2 . . . . . divide by 2

  17 = a . . . . . . . . add 2

Sides FJ and HJ are congruent, so we have ...

  FJ = HJ

  3b +6 = 24 . . . . substitute given values

  b +2 = 8 . . . . . . divide by 3

  b = 6 . . . . . . . . . subtract 2

The values of a and b are (a, b) = (17, 6).

28

step-by-step explanation:

because that's the answer

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
