triangle STU is an equilateral triangle. If ST is one less than twice x, SU is 37 less than five times x, and TU is 11 more than
maks197457 [2]

Answer:

The value of x = 12 and the measure of each side is 23 units.

Step-by-step explanation:

Given:  STU is an equilateral triangle.

ST = 2x -1

SU = 5x - 37

TU = x + 11

Now, as Δ STU is an equilateral triangle, hence all the sides of the triangle are equal.

⇒ ST = SU = TU

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

Considering : 2x -1 = 5x - 37 , we get

-1 + 37 = 5x - 2x

or 3x = 36

or, x = 12

Considering : 5x - 37 = x + 11 , we get

5x -x = 11 + 37

or, 4x = 48  or, x = 12

Considering :  x + 11  = 2x -1

or, 2x - 1 =  x + 11

or, x = 12

hence, in all the cases value of x = 12

ST =  2x -1 =  2(12) -1  = 23 units

SU =  5x - 37= 5(12) -1  = 23  units

TU =  x + 11  = 12 = 11  = 23 units
