triangle relationship

Question

stu is a equilateral triangle if st is one less then twice x su is 37 kess than five times x and tu is 11 more than x find x and the measure of each side

Answer 1

ST = SU = TU

2x - 1 = 5x - 37 = x + 11

2x - 1 = x + 11

x - 1 = 11

x = 12

st = 2x-1 = 23

2x + 1 = 25

2x = 24

x = 12

su = 5x - 37 = 23

2x - 1 = x + 11

x = 12

tu = x+11 = 23

The measure of each side ix 23 (yes, the it is an equilateral triangle).
