Jkl is an equilateral triangle jk = 13x+5, KL = 17X-19 AND JL = 8X+35

x = 6

Step-by-step explanation:

Since the triangle is equilateral then sides are congruent.

Equate any 2 sides and solve for x

13x + 5 = 8x + 35 (subtract 8x from both sides)

5x + 5 = 35 (subtract 5 from both sides)

5x = 30 (divide both sides by 5)

x = 6

JK = (13 * 6) + 5 = 78 + 5 = 83

KL = (17 * 6) - 19 = 102 - 19 = 83

JL = (8 * 6) + 35 = 48 + 35 = 83

ΔJKL is equilateral with side = 83
