Find the value of b. Express the answer as a simplified radical.

Mama L [17]

Here three sides of a right angled triangle given.

The three sides are b, 8 and 14.

The side with length 14 is the hypotenuse here. We have to find the side of length b.

To get b, we will use Pythagoras theorem here.

By using Pythagoras theorem we can write,

$c^2=a^2+b^2$ , where c is the hypotenuse.

So here we can write,

$14^2=8^2+b^2$

$196 = 8^2+b^2$

$196=64+b^2$

To solve it for b, now we have to move 64 to the left side by subtracting it from both sides.

$196-64 = 64+b^2-64$

$196-64 = b^2$

$132=b^2$

Now to find b, we have to take square root to both sides. We will get,

$\sqrt{132}= \sqrt{b^2}$

$\sqrt{132} =b$

$b= \sqrt{(4)(33)}$

$b= (\sqrt{4})(\sqrt{33})$

$b= 2\sqrt{33}$

We have got the required answer for the side b.

Triangles ABC and DEF are similar triangles. What are the lengths of the unknown sides? Question 10 options: A) DE = 24 yd.; EF

Nataly_w [17]

Answer:

D)DE=24 YD.;EF=10yd

Step-by-step explanation:

AB=12 FT SO YOU DO 12*2 AND YOU GET 24 ON DE

CB=5 FT SO YOU DO 5*2 AND YOU GET 10

I need to know How I can do this Please don't just write the answer explain what part of of the quadratic standard equation mean

makvit [3.9K]

It is a negative graph and if you take the peak- the y intercept, it gives you the value of b. make that value negative and you should get your answer. i also put my answer in the comments if you wanted it, but you said you didn’t so..
