Studentka2010 [4]

Answer:

Step-by-step explanation:

first, you have to recognize that the two angles will be the same.   They are like that b/c of how they are opposites.    next , b/c they are the same , set them equal to each other and then solve the equation for x ( isolate x)

29 = 4x -1

29 + 1  = 4x -1 + 1

30 = 4x

30/4   = 4x /4

7.5 = x

now to find ∠DCE  just plug in x, but you also can just observe that ∠DCE is going to be 29° b/c the angle opposite of it is also.

elena-14-01-66 [18.8K]

Answer:

  5x +4y

Step-by-step explanation:

The perimeter of a triangle is the sum of side lengths. That fact can be used to find z, the length of the third side.

  (2x +3y) +(5x -2y) +z = 12x +5y . . . . sum of sides is perimeter

  z = (12x +5y) -(7x +y) . . . . . . . . . . . . subtract (7x+y) from both sides

  z = 5x +4y . . . . . . . . . collect terms; the length of the third side

The third side of the triangle is (5x +4y).
