Question

in a square, CDAB calculate the angles marked with small letters in the following diagram.​

Answer 1

Answer:

Diagonals of a rectangle are equal and bisect each other

Thus, ∠OBA = ​∠OAB = 21 deg

Now, all angles of a rectangle are right angles.

Thus, ∠CBA = 90 deg

21 deg + x = 90 deg. x=69° 3.x+34+90=180 in triangle PLQ

x+124=180

x=180-124

x=56

x=y

so,x=56 and y =56.
