Question

two sides being given, calculate the third side marked by a letter in each right angled triangle​

Answer 1

Answer:

Sum of the square of the smaller sides is equal to the square of the largest side.. The largest side is called the hypotenuse

Answer 2

Answer:

By Pythagoras theorem.

Step-by-step explanation:

let unknown side be 'x'.

when it is the hypotenuse

then: x2=square of one side + square of the other side

when it is base or perpendicular

then: hypotenuse = square of one side + square of x
