Step-by-step explanation:

(\sqrt{5} - \sqrt{2})(\sqrt{2} + \sqrt{5})\\\sqrt{5} (\sqrt{2} + \sqrt{5}) - \sqrt{2} (\sqrt{2} + \sqrt{5})\\\sqrt{5} * \sqrt{2} + \sqrt{5} * \sqrt{5} - \sqrt{2} * \sqrt{2} +\sqrt{2} * \sqrt{5}\\ \sqrt{5*2} + \sqrt{5*5} - \sqrt{2*2} - \sqrt{2*5}\\\sqrt{10} + \sqrt{25} - \sqrt{4}  - \sqrt{10}

plus root 10 and minus root 10 gets cancel . So,

\sqrt{25} - \sqrt{4} \\\sqrt{5^{2} } - \sqrt{2^{2} }

square and root gets cancel

What is the altitude of an equilateral triangle with a side length of 10 in.
LenaWriter [7]

Good morning,

Answer:

\frac{\sqrt{3} }{2} a

Step-by-step explanation:

h = altitude

side = a

using Pythagorean theorem: in the right triangle:

h² = a² - (a/2)²

    = a² - a²/4

    = 3/4a²

    = [(√3/2)×a]²

⇒ h = (√3/2)×a.
