Intermediate Geometry : How to find the height of an equilateral triangle Equilateral triangles have sides of equal length, with angles of 60°. To find the height, we can draw an altitude to one of the sides in order to split the triangle into two equal 30-60-90 triangles. Now, the side of the original equilateral triangle (lets call it a) is the hypotenuse of the 30-60-90 triangle.

- Stop and measure the distance that you are from the tree. This distance is equal to the height of the tree less your height. So find out how tall you are, add this to the distance from the tree and you have an accurate measurement of the tree height.top when you are at a point where you can just see the top of the tree and measure the distance along the ground from the tree to you. This is roughly equal to the tree’s height. Method 3 Ratio stick. Cut a strip of card so that it is exactly 30cm long and approximately 3-4 cm wide.

How does one calculate a television's height and width based on its diagonal length and aspect ratio? Understand aspect ratio and how it relates to TV size. Aspect ratio is the ratio of the display image’s width to its height. There's a difference in aspect ratio between older, standard TV models and newer, widescreen models. Most standard TVs use an aspect ratio of 4:3 for their screens. That means for every 4 inches of width of screen, you will have 3 inches of height.

How to Determine the Length of a Shadow Rewrite the following formula with the numerical equivalents: Object Height / Sun Tangent = Shadow Length. For example, for the 790-foot high Prudential Tower in Boston, the formula would be 790 / 2.89 = Shadow Length. Calculate the formula to determine the shadow length. For example: 790 / 2.89 = 273.36 feet. Because the height of the Prudential tower was given in feet, the calculated length of the shadow is also in feet.

Homework Help: Finding height of image for a concave mirror Ok, theres something I just don't understand. I know that to find the height of an image (hi), you need to use the magnification equation m = -di/do = hi/ho. And for this question, the focal length (f), distance of object (do), and distance of image (di) are given. Now, if I want to find the height of the image (hi), I would need the height of the object (ho) to finish the equation, but I don't, so now I'm stumpted on what to do with this question.

- Step Two: Enter 11 inches in the width field of the scan setup window destination or target section. You will see a corresponding height of 16.38 inches. If you were to enter 14 inches in the height field, the image width would only be about 9 inches, not large enough for your target photo enlargement.ou can crop the photo enlargement to the exact print size later in Photoshop. Step Three: Check the scale or percentage field of the scan setup and you will see the dimensions you entered in the target size fields produce a 273% photo enlargement.
