Question

kindly solve the part "b" of this question.​

Answer 1

Answer:

Hope this helps....

angle A=B=C=D= 90 DEGREE

angle DCA = 1/2 * 90 = 45 degree

c+c = 180 - 45 (ASP)

c = 135/2

angle c = 67.5 degree

angle d = 90 - c = 90 - 67.5

angle d = 22.5

Answer 2

Answer:

Hey mate! The answer  to your question is ∠C = 67.5° ∠D = 22.5°.

Step-by-step explanation:

We know that diagonals bisect each other.

So,

∠FCE = 45°.

Using angle sum property in ΔFCE,

∠C + ∠C + ∠FCE =180°

2∠C + 45° = 180°

2∠C = 180° - 45°

2∠C = 135°

∠C = 67.5° ---------------------- 1

We also know that,

∠D = 90° - ∠C

∠D = 90 - 67.5 ( From 1 )

∠D =22.5°
