12 is correct , very good! Welcome to the forum.

]]>What do you need?

]]>I have drawn your rectangle below, click on it to enlarge it. If my drawing is correct then to find AB you use the pythagorean theorem where c is AB.

Take the square root of both sides,

So AB = 1.4422205101 cm.

Do you know how to round that to the nearest hundredth?

]]>The first problem is a rectangle and it has a dotted line going from the bottom of the left corner (it has an A right next to it) to the top of the right corner ( it has a B right next to it). The bottom lenght of the rectangle measures 1.2 and the right side measures .8. The dotted line in the middle forms two triangle in the rectangle. Please someone help me!

]]>Is this a right triangle?

]]>I have edited the post you refer to as you are quite correct; it was wrong mathematically.

But I have also removed your remarks as they were also unnecessarily rude.

Why not join the forum and make a contribution.

So by following the formula given before:

Where:

a and b are the sides and c is the hypotenuse.

So you have sides a=12 and b=9.

im stupid

it took me forever to figure this out

Welcome to the forum!

I suppose that the trianglw you are talking about is a right triangle.

Do you know the Pythagorean theorem?

]]>What is the missing side length if a= 10 b= 24 and c= x

a. 26

b. 36

c. 40

d. Square root of 124

Please help, not sure what to do ]]>

Welcome but I am sorry his answer is correct and yours is not. You are not using the pythagorean theorem correctly.

Please be more careful and tactful in correcting previous posts.

use the pythagorean formula (a² = b² + c²)

a= hypotonuse

b= side

c= side

therefore

26² = 10² + x²

676 = 100 + x²

x² = 576

x = 24

[Incorrect, and rude, comment removed by moderator]

l a²+b²= c²

l =

l =

l = 26

10 l =

l_ =

l_l___________=

X=4:D

[24 is correct]
