We are a given a right angles triangle which has side lengths 7 units each (of the perpendicular and the base) and we are supposed to find the length of the hypotenuse.
We can find the length of the hypotenuse by using the Pythagoras Theorem:
where is the hypotenuse and and are the perpendicular and base.
Therefore, the length of the hypotenuse id 9.89 units.
X^2+5x=2 you then solve by completing the square using the formula (b/2)^2 in order to create the new term. Solve for x by using this term to complete the square. Your answer is then x=-5/2+-√33/2
