Question

If ∠I≅∠K, find the perimeter of ΔJIK.

Answer 1

23

Explanation:

The sides opposite equal angles of a triangle have equal length:

KJ = IJ

9x -11 = 6x -5

3x = 6 . . . . . . . . add 11-6x

x = 2

__

Perimeter = (7x-5) +(6x -5) +(9x -11) = 22x -21 = 22(2) -21 = 23

The perimeter of triangle JIK is 23 units.
