Answer:

<em>4 is the unit's digit of the 20th number.</em>

Step-by-step explanation:

Let us try to find out a pattern for the unit's digit of the terms.

1st term is 1, so unit's digit of 1st term is 1.

2nd term $1^{2} + 3 = 4$ so unit's digit is 4.

3rd term $4^{2} + 3 = 19$ so unit's digit is 9.

4th term $19^{2} + 3 = 364$ so unit's digit is 4.

5th term's unit digit: Square of unit's digit of 4th term + 3

$4^{2} + 3 = 19$ i.e. 9.

We can see that the pattern is

3rd, 5th, 7th ...... terms have 9 as the unit's digit.

2nd, 4th, 6th.... terms have 4 as the unit's digit.

So, 20th term will have 4 as the unit's digit.

elena55 [62]

Answer:

C. 27°

Step-by-step explanation:

This question can be solved by using the concept of law of reflection which states that any ray of light reflects from the surface then angle of incidence is equal to angle of reflection.

In the problem given above angle of incidence as given is 27 degrees.

therefore by using law of reflection angle if reflection will be equal to angle of incidence i.e 27 degrees.

Thus, correct option is C. 27°
