This is the kite. The kite has two pairs of sides of equal length.
TE = TI and KE = KI.
Therefore we have the equation:
14x - 19 = 12x + 35 |add 19 to both sides
14x = 12x + 54 |subtract 12x from both sides
2x = 54 |divide both sides by 2
x = 27
IT = 12x + 35
put the value of x to the expression:
IT = 12(27) + 35 = 324 + 35 = 359
