Question

Express $75°$ angle in seconds.

Answer 1

As we know that -

$1°=60\prime (1degree=60minutes)$ and

$1\text{'}=60\text{'}\text{'}(1minute=60seconds)$

So $75°=75°\times 60\text{'}=4500\text{'}$

$4500\text{'}=4500\text{'}\times 60\text{'}\text{'}=270000\text{'}\text{'}$

Hence, $75°$ is equal to $270000\text{'}\text{'}$.
