Find the exact length of the third side.<br> 51
Nesterboy [21]

Answer:

24

Step-by-step explanation:

You can use the Pythagorean Theorem to solve this:

a^{2} + b^{2} = c^{2}

The legs of the triangle are put into either a or b and the hypotenuse is put into c. In this case, they've already given you the hypotenuse, but now you need to find the leg:

45^{2} + b^{2} = 51^{2}

2025 + b^{2} = 2601

<em><u>Subtract 2025 from both sides:</u></em>

2025 + b^{2} = 2601

-2025       -2025

_____________

b^{2} = 576

<em><u>Square root:</u></em>

\sqrt{b^{2} } = \sqrt{576}

b = 24

Cerrena [4.2K]

Answer:

<u><em>x=9</em></u>.

<em><u>perimeter=68</u></em>

<em><u>area=168</u></em>

Step-by-step explanation:

First find the side that has a exact number which would be the bottom 28cm then look at the opposite side (2x+10) in order to find x subtract 10 from 28 which gives you 18, now 2x means x multiplied by 2 so what multiplied by 2 = 18? 9 meaning <u><em>x=9</em></u>. Now you are going to want to plug 9 in to your short side (x-3) once you plug it in it should look like this 9-3 and 9-3=6 meaning the short side is 6cm. In order for you to find the perimeter you have to add the sides together so 28+28+6+6 wich <u><em>=68</em></u> and in order for you to find the area you have to  multiply the length and the width so 28x6 which is <em><u>168</u></em>.

hope that helped :)
