A
B
(A) 15°
(B) 30°
(C) (22)
(D) 45°​

Answer 1

Answer:

(A) 15°

Step-by-step explanation:

EBC is an equilateral triangle so ebc=60°, ABCD is a square so abc=90°, abe=(90°+60°) or 150°. Because of being a square and equilateral triangle ab=bc. Now 180°-150°=30°, 30°/2=15°.

So the answer is 15°.
