A TV screen is 41 cm long and 31 cm high. The length of the diagonal is closest to: A) 49 cm Eliminate B) 51 cm C) 54 cm D) 48 c
GuDViN [60]

Answer:

The length of the diagonal is closest to 51 cm.

Step-by-step explanation:

Given:

TV screen is 41 cm long and 31 cm high.

Now, to find the length of the diagonal.

By using pythagorean theorem:

leg 1 = 41 cm, leg 2 = 31 cm.

Let the hypotenuse be x.

(leg 1)² + (leg 2)² = hypotenuse²

41^{2} +31^{2}=x^{2}

⇒1681+961=x^{2}

⇒2642=x^{2}

<em>Using square root on both sides we get:</em>

⇒51.40=x

<u><em>So, the length of the diagonal = 51.40 cm. </em></u>

<u><em>By rounding off of 51.40cm it becomes 51 cm.</em></u>

Therefore, the length of the diagonal is closest to 51 cm.

Helppp pleaseeeee!!!!!!!

I’m pretty sure all you have to do is plug in your numbers for example number 5 is y=2x-2 so you would plug in the first number which is -1. So the equation that you solve would be y=2 times -1 minus 2. That would be -4. I hope this helps. If you need further explanation please say so in comments.
