Divide this number by the sine of angle A to find the length of side B. For the example, angle A measured 30: sine 30 = 0.5: 7.1/0.5 = 14.2 inches for the length of side B. Step 5 Repeat the procedure using angle C instead of angle B to find the measure of the side opposite ...
(a) Calculate the length of each side of the right triangle, and (b) Show that these lengths satisfy the Pythagorean Theorem. The Pythagorean Theorem in Coordinate Geometry: Consider a right triangle on a grid consisting of vertices {eq}A\...

The area of any object depends on the shape and properties of the object. The area is different for different objects. For example, the area of the circle is {eq}\pi r^2 {/eq} where {eq}r {/eq} is the radius of a circle and the area of the triangle is {eq}\frac{...

It can help you find the length of a side of a right triangle as long as you have an angleθ\thetaθand some info on the other sides of the triangle. Example problems In this chapter, we're actually going to focus on the cosine rule. This means we'll only be working with the "...

Calculating Sides of Right Triangles Step 1 Recall the Pythagorean Theorem. You can calculate the length of any side of a right triangle if you know the lengths of two sides using the pythagorean theorem. In addition, you can determine if a triangle has a right angle (90 degrees) if it ...
To calculate the area of a triangle in Excel, you need to use this formula=(<cell with length>*<cell with height>)/2. If the length is given in the A1 cell and height in the B1 cell, you need to use the formula like this:=(A1*B1)/2. No matter how many cells there are with...
