If ORBIT is coded BEOVG, then how is PLANET coded? / 1. CYNARG

2. CONAVG

3. CYNAVG

4. XONARG

1. CYNARG

Step-by-step explanation:

This a example of Caesar's Cipher, in which each letter in the original word leads to a ciphered letter according to the following equation:

In which C is the index of the Ciphered letter in the alphabet, P is the index of the original letter and o is the offset.

Finding the offset:

O is coded B

O is the 15th letter in the alphabet, so .

B is the 2nd letter in the alphabet, so

So

PLANET:

P

P is the 16th letter in the alphabet.

So P is coded C.

L

L is the 12th letter in the alphabet:

L is coded Y(25th letter in the alphabet)

A

A is the 1st letter in the alphabet

A is coded N

N

N is the 14th letter in the alphabet

N is coded A

E

E is the 5th letter in the alphabet

E is coded R

So the correct answer is:

1. CYNARG

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
