## What is the length of the longest side of a right triangle?

In a right triangle, the hypotenuse will always be the longest side, so here it must be 17 yards.

**What is the missing side length in this right triangle?**

Finding the missing side of a right triangle is a pretty simple matter if two sides are known. One of the more famous mathematical formulas is a2+b2=c2 a 2 + b 2 = c 2 , which is known as the Pythagorean Theorem.

### How do you find the unknown length of a right triangle?

How to find the sides of a right triangle

- if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² – b²)
- if leg b is unknown, then. b = √(c² – a²)
- for hypotenuse c missing, the formula is. c = √(a² + b²)

**What are the rules for a 45 45 90 triangle?**

The main rule of 45-45-90 triangles is that it has one right angle and while the other two angles each measure 45° . The lengths of the sides adjacent to the right triangle, the shorter sides have an equal length.

## What is the missing length of this right triangle?

**How to find missing side length?**

If you have the hypotenuse,multiply it by sin (θ) to get the length of the side opposite to the angle.

### How to find angles using side lengths?

h2+ a2- 2ax + x2= b2. Using the first equation replace x2+ h2by c2then using the third equation replace x by a – b cos(C). Simplify to get. c2= a2+ b2- 2ab cos(C) This is the Law of Cosines. If you know the side lengths a, b and c you can find cos(C) and hence the measure of the angle C. Harley.

**How do you find missing side length of a triangle?**

– Solution : So, the measure of missing side is 4.6. Find the measure of each side indicated. Round to the nearest tenth. – Solution : Opposite side = AC = 10.8 So, the measure of missing side is 13. Find the measure of each side indicated. – Solution : Hypotenuse side = AB = 10.3 So, the measure of missing side is 6.1.
