Use Pythagoras theorem to work out the hypotenuse when the adjacent length of a triangle is 3 and the opposite side is 4.

using the Pythagoras formula: a^2 + b^2 = c^2 the longest measurement is always the hypotenuse due to the orientation of a triangle and so c is the hypotenuse leaving the a and b to be the two measurements within the question:3^2 + 4^2 = 2525=c^2 . square root both sides to get c 5=cthe hypotenuse is 5
