Question

BEC is an equilateral triangle in the square ABCD.Find the value of x in degrees​

Answer 1

Answer:

"Renaissance" comes from the French word for "rebirth." According to the City University of New York at Brooklyn, intense interest in and learning about classical antiquity was "reborn" after the Middle Ages, in which classical philosophy was largely ignored or forgotten. Renaissance thinkers considered the Middle Ages to have been a period of cultural decline. They sought to revitalize their culture through re-emphasizing classical texts and philosophies. They expanded and interpreted them, creating their own style of art, philosophy and scientific inquiry. Some major developments of the Renaissance include astronomy, humanist philosophy, the printing press, vernacular language in writing, painting and sculpture technique, world exploration and, in the late Renaissance, Shakespeare's works.

Answer 2

Step-by-step explanation:

We know that:-

All internal angle of squire is 90° .

All internal angles of equilateral ∆ is 60°.

Diagonal bisect the angle in a square is 45°.

OBC= 45°(diagonal segment)

BCO=60° (since, BEC is an equilateral ∆)

So in ∆OBC,

=> OBC+BCO+X= 180°

=> X=180°-60°-45°

=> X=75°
