The bases of a trapezium are parallel to each other.
The line x is parallel in this trapezium.
Hence,
Given two sides
- If leg a is the missing side, then transform the equation to the form where 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)
I think you should provide extra information for correct answer.
that the angles etc.
