Question

The angle by which turns clockwise about point b to coincide with is 63.9 degrees. if from point b, a point e is drawn directly opposite point c so that b, e, and c are on the same straight line, the angle by which turns counterclockwise to coincide with is 243.9 degrees.

Answer 1

AB turns clockwise to coincide with BC.

To find the angle by which turns counterclockwise to coincide with is 243.9 degrees:

An angle -

• An angle is a figure in Euclidean geometry created by two rays, called the sides of the angle, that share a common termination, called the vertex of the angle.
• Angles formed by two rays are located in the plane containing the rays.
• Angles are also generated when two planes intersect.
• These are known as dihedral angles.

So,

= ABD + DBC

= 33.3° + 30.6°

= 63.9°

b) If E is drawn directly opposite C.

EBC is a straight line, so the sum of angles =180°

ABE + ABD + DBC = 180°

ABE + 33.3° + 30.6° = 180°

ABE + 63.9° = 180°

ABE = 180 - 63.1

ABE = 116.9

Therefore, AB turns clockwise to coincide with BC.
