Given AE is parallel to DC and BE is parallel to AD, ∠ ABC = 73°, C = 97° To find : ∠ EBF Since AE is parallel to DC ∴ 110° + ∠ DAE = 180° (Co-interior ∠'s) Also, ∠ BEA = ∠ DCF = 97° (Corresponding B ∠'s) ⇒ ∠ BEA = 97° Now in Δ ABF, ∠ FAB + ∠ ABF + ∠ AFB = 180° (Angle Sum Property) ⇒ ∠ FAB + 73° + 97° = 180° ⇒ ∠ FAB = 180°-170° ⇒ ∠ FAB = 10° Now, AD is parallel to BE (Given) ∴ ∠ DAB + ∠ ABE = 180° ( Co-interior angles) ⇒ ∠ DAF + ∠ FAB + ∠ ABF + ∠ EBF = 180° ⇒ 70° + 10° + 73° + ∠ EBF = 180° ∠ EBF = 180°- 153° ∠ EBF = 27°

Development is a process that creates growth, progress, positive change or the addition of physical, economic, environmental, social and demographic components.
The cognitive changes that take place in a developing child are as follows:

0-2 years: This is the age of sensory motors whereby, infant explores the world by coordinating sensory experiences with physical actions.
2-7 years: In this age, Preoperational thinking begins and the child acquires the concept of object permanence that enables him/her to use mental symbols to represent objects. The child does not have the ability to judge or assume the consequences of actions before performing them.
The child also acquires preoperational thought, i.e., s/he gains the ability to mentally represent an object that is not physically present.
The children are egocentric and develop animist thought
4-7 years: Children develop intuitive thought. This enables them to question the things happening around them.
7-11 years: This age is marked by the development of concrete operational thought, whereby a logical thought is developed and the child can reason logically about concrete events, classify objects into sets and perform reversible mathematical operations.
11-15 years: The adolescents in this age develop formal operational thought, which leads to hypothetical thinking and is able to apply logic abstractly. They also develop a special kind of egocentrism of imaginary audience and personal fable.

A traditional Russian wedding can last between two days and one week. The celebration involves dancing, singing, toasting, and banqueting. The best man and maid of honor are called Witnesses or "svideteli" in Russian. The ceremony and the ring exchange take place on the first day of the wedding.

A traditional Indian wedding lasts an average of three days. Every wedding guest is usually invited, and it involves an introduction of the couple's families, mingling, a meal and dances or other performances. On the third day, the main ceremony, cocktail hour and reception take place.

Laws of inertia decided into three laws. In the first law, an object will not change its motion unless a force act's on it. In the second law, the force an object is equal to its mass times its acceleration. In the third law, when two objects interact they apply forces to each other of equal magnitude and opposite direction.
