Kaylis [27]

Answer:

reflex angle

Step-by-step explanation:

Acute is less than 90

Right = 90

Obtuse is greater than 90 and less than 180

Straight is 180

Reflex is greater than 180 and less than 360

This is greater than 90 and less than 180 so it is a reflex angle

An algorithm takes 5 seconds for input size 200. How long will it take for input size 1000 if the running time is linear (assume
tankabanditka [31]

The running time for an input size of 1000 will be 25 seconds.

To calculate the runtime of the Algorithm we need to know what an Algorithm is and how its runtime works.

<h3>What is the runtime of an Algorithm?</h3>

A finite sequence of rigorous instructions, used to solve a critical problem of a specific class or for computational purposes is called an Algorithm. The time taken to complete the said task is called the runtime of an Algorithm.

Let us now solve the question about linear running time of an algorithm.

Input size(N_{1})=200

Time taken(T_1)=5 seconds

Final input size(N_2)=1000

Let the final time taken be T.

Now we know that: \frac{N_1}{T_1}=\frac{N_2}{T_2}

Substituting the values we get T_2=25 seconds .

Therefore the linear running time for an input size of 1000 is 25 seconds.
