<h3>Answer:  2\sqrt{5}</h3>

======================================================

Explanation:

Both legs are the same length, as indicated by the tickmark.

  • a = \sqrt{10}
  • b = \sqrt{10}
  • c = x

Use the pythagorean theorem to solve for x

a^2+b^2 = c^2\\\\( \sqrt{10} )^2 + ( \sqrt{10} )^2 = x^2\\\\10 + 10 = x^2\\\\x^2 = 20\\\\x = \sqrt{20}\\\\x = \sqrt{4*5}\\\\x = \sqrt{4}*\sqrt{5}\\\\x = 2\sqrt{5}\\\\

Natali5045456 [20]

Answer: 63

Step-by-step explanation: To find 70% of 90, first write 70% as a decimal by moving the decimal point two places to the right to get .70.

Next, the word "of" means multiply, so we have (.70)(90) which is 63.

So 70% of 90 is 63.
