Quadrilateral ABCD is a square, triangle CDE is an equilateral triangle. Find the degree of angle AEB I can't send the picture, but describe it. A square (adce in clockwise) is connected with an equilateral triangle Dec on the left
∵ △ CDE is an equilateral triangle
∴∠CDE=60°
ABCD is a square
∴∠ADC=60°
∴∠ADE=150°
∵DA=DC=DE
∴∠AED=15°
Similarly, CEB = 15 degree
∴∠AEB=60°-15°-15°=30°
