Question

ABCD is a rectangle. Find the value of x and y ​

Answer 1

Answer:

135 degrees and 45° respectively

Answer 2

Answer:

L AED = L EDC                              ∵ ALT. INT. ANGLES

L AED = L ADE                           ∵ angles opposite to equal sides are equal

∴ L EDC = L ADE

L EDC + L ADE = 90°                  ∵ EVERY ANGLE IS A RIGHT ANGLE

y + y = 90°

2y= 90°

y = 45°

L ADE = L AED                              ∵ ANGLES OPPOSITE TO EQUAL SIDES                                                                               .                                                         ARE EQUAL

L AED + L DEB = 180°

y + x = 180°

x=180°- 45°

x = 135°
