Find the missing length.

To find the missing length of this triangle you need to use the Pythagorean Theorem.

As shown in the image we are given three sides: 1, 8 and c and so you have to substitute these numbers into the equation a squared + b squared = c squared.

So it should look like:

1 squared + 8 squared = c squared, so solve it to be

1 + 64 = c squared which is 65 = c squared

Now you have to isolate the variable c because that is what you are trying to find so you must square root both sides:

\sqrt{65} = c

So that should be your answer.

Hope this helps!

(if it doesn't work then you might have to simplify)

Firewood can be sold in cords. the wood is cut into equal lengths and stacked evenly in a rack. which geometric shape can be use
Nadya [2.5K]

To estimate the volume of the chord of wood, since the wood exists cut into equal lengths and stacked evenly in a rack then we can use a cylinder as a model.

<h3>What is a cylinder?</h3>

In mathematics, a cylinder exists as a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance. These bases exist normally circular (like a circle) and the center of the two bases exists joined by a line segment, which exists named the axis.

A cylinder exists as a closed solid that contains two parallel circular bases joined by a curved surface.

To calculate the volume of the chord of wood, since the wood exists cut into equal lengths and stacked evenly in a rack then we can use a cylinder as a model.

Lostsunrise [7]

Answer:

Step-by-step explanation:

AB^2 = HB^2 + AH^2 => AB = 15cm

Ta co cong thuc: 1/AH^2 = 1/AB^2 + 1/AC^2 => AC=20cm

Vay SABC= 1/2 .AB.AC = 1/2 .15.20=150cm^2
