Question

I need help on a and b

Answer 1

Given:

<EBC = 27° and <ADE = 52°

a)

A kite, their diagonals are perpendicular (AC⊥ BD) so < BEC = 90°

<BCE = 90 - 27

<BCE = 63°

b)

Because AB = AD so triangle ABD is an isosceles triangle then <ABE = <ADE = 52°

<BAD = 180 - 2(52°)

<BAD = 180° - 104°

<BAD = 76°
