Question

For the following right triangle, find the side length x.XO68

Answer 1

Using the Pythagoras theorem,

opposite² + adjacent² = hypotenuse²

From the figure given,

opposite =6 adjacent=8 hypotenuse=x

Substitute the values and evaluate

6² + 8² = x²

36 + 64 = x²

100 = x²

Take the square root of both-side

10 = x
