Question

4 seconds (unit of angle) is equivalent to (1) 1/900 degree (2) 1/300 degre


guys plz solve step by step

Answer 1

Before going to solve we must know

1 degree = 60 minutes

1 minute = 60 seconds

Hence

1 degree = 3600 seconds

==> 1 second = 1 / 3600 degrees

Multiplying both sides by 4

4 seconds = 4 / 3600 degrees

4 seconds = 1 / 900 degrees

I hope this answer helps you

Answer 2

Answer ⇒ Option 1. 900°

Explanation ⇒

We know, 1'' (or 1 seconds) is equals to 1/60'
 and 1' = 1/60°

∴ 1'' = 1/60 × 1/60
       = 1/3600°

Now, 4'' = 4 × 1/3600°
              = 900°

Hence, Option 1 is correct. 


Hope it helps.
