In a certain triangle the longest side is twice as long as the shortest side and the shortest side is 4 inches shorter than middle side. If the perimeter of the triangle is 52 inches how long is the longest side?

24 inches

Step-by-step explanation:

Let the longest side be x, the middle side be y and the shortest side be z

Rest is in the attached file

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
