For a rectangle, the two verticle sides should be congruent (of the same length)

2y+4=10

Subtract 4 from both sides
2y=6

Divide both sides by 2
y=3

Final answer: 3

The value of y in the triangle is 3

Properties of a rectangle:

  • Opposite sides are equal
  • all the angles are 90 degree each
  • The sum of the angles is 360 degrees

Therefore,

2y + 4 = 10

2y = 10 - 4

2y = 6

y = 6 / 2

y = 3

10 + 2x = 18

2x = 18 - 10

2x = 8

x = 8 / 2

x = 4
