Maths · Straight line: Various forms of equations of a line, intersection of lines, angles between two lines

In the given figure Find if all measurements are indicated in centimeter.

In the given figure \( A B \| C D . \) Find \( x+y \) if all measurements are indicated in centimeter.

  • A. \( 4.5 \mathrm{cm} \)
  • B. 7.5 \( \mathrm{cm} \)
  • C. 6 .5 \mathrm{cm} \)
  • D. \( 2.75 \mathrm{cm} \)

Step-by-step solution

Since AB || CD, using properties of similar triangles formed by the intersection of diagonals (or by dropping perpendiculars), we set up proportions based on given lengths. Solving yields x = 3 cm and y = 4.5 cm, so x + y = 7.5 cm.
