since the triangle is equilateral, it means the 3 sides of the triangle are of the same length. BE is a side of the triangle, and also a side of the square. a square has 4 equal sides, which means that BE = BC and that ABC is an isosceles triangle. therefore the answer is (180° - 150°)/2 = 15°
I got it! Thank u! Good night!
you're welcome!
