Question

Find the length of the missing side.

  1. 25 cm
  2. 42 cm
  3. 52 cm
  4. 48 cm

hintHint:

Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. Using this we can find the missing side.

The correct answer is: 52 cm


    APQ,
    h squared equals p squared plus b squared
h squared equals 20 squared plus 48 squared
space space space space space space equals 400 plus 2304
space space space space space space space equals 2704
h equals 52
