1.	In the adjoining figure ABCD is a square and EBC is an equilateral triangle. The measure of ZEABis equal toEAB(A) 15°(B) 30°(C) (22)(D) 45°
Answer» 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°.
