As shown in the figure, in the rectangular ABCD, AE ⊥ BD, the perpendicular foot is e, ∠ DAE = 3 ∠ BAE, can you find out the degree of ∠ DAE and ∠ BAE? Have proof!

As shown in the figure, in the rectangular ABCD, AE ⊥ BD, the perpendicular foot is e, ∠ DAE = 3 ∠ BAE, can you find out the degree of ∠ DAE and ∠ BAE? Have proof!

Because it is a rectangle, the angle bad = 90 degrees, i.e
∠ DAE + ∠ BAE = 90 degrees
And ∠ DAE = 3 ∠ BAE,
So ∠ DAE = 67.5 degrees
∠ BAE = 22.5 degrees
