## How do you find the missing length indicated?

The Pythagorean theorem states that a2 + b2 = c2 in a right triangle where c is the longest side. You can use this equation to figure out the length of one side if you have the lengths of the other two. The figure shows two right triangles that are each missing one side’s measure.

## What can you use to find a missing side length of similar polygons?

Typically, problems with similar polygons ask for missing sides. To solve for a missing length, find two corresponding sides whose lengths are known. After we do this, we set the ratio equal to the ratio of the missing length and its corresponding side and solve for the variable.

## How do you find the side lengths of similar triangles?

Calculating the Lengths of Corresponding Sides

1. Step 1: Find the ratio. We know all the sides in Triangle R, and. We know the side 6.4 in Triangle S.
2. Step 2: Use the ratio. a faces the angle with one arc as does the side of length 7 in triangle R. a = (6.4/8) × 7 = 5.6.

## How do you find two missing variables in an equation?

Divide both sides of the equation to “solve for x.” Once you have the x term (or whichever variable you are using) on one side of the equation, divide both sides of the equation to get the variable alone. For example: 4x = 8 – 2y. (4x)/4 = (8/4) – (2y/4)

## How do you find the length of a missing triangle?

You can use this equation to figure out the length of one side if you have the lengths of the other two. The figure shows two right triangles that are each missing one side’s measure. In the left triangle, the measure of the hypotenuse is missing. Use the Pythagorean theorem to solve for the missing length.

## How do you solve the missing length problem?

Use the Pythagorean theorem to solve for the missing length. Replace the variables in the theorem with the values of the known sides. Square the measures and add them together.

## How to find missing coordinates using distance formula?

Find the value of a if the distance between the points at (7, 5) and (a, -3) is 10 units. So, the missing coordinates are 1 or 13. Find the value of a if the distance between the points at (3, -1) and (a, 7) is 10 units. So, the missing coordinates are 9 or -3.
