Question

Please solve it on a clear piece of a paper! Please!

Answer 1

The diagonals of a rectangle are congruent and bisected each other.

So, triangle ADE is an isosceles triangle .

The base angles of an isosceles triangle are congruent.

So, angle ADE=DAE

Since vertical angles are congruent, angle ADE = angle BEC = 52°

Therefore,

Angle ADE + DAE + AED = 180°

Angle ADE + ADE + 52°= 180°

2 ADE + 52° = 180°

2 ADE = 180°- 52°

2 ADE = 128°

ADE = 64°

ADE = ADB = 64°

DAE = ADE

ACD = 90° - DAE

ACD = 90° - 64°

ACD = 26°

Hope this would help you.
