Answer:

Step-by-step explanation:

We have 5 squared minus (3 squared plus 4). Convert this to mathematical expression:

- "5 squared" = 5²

- "minus" = -

- "3 squared" = 3²

- "plus 4" = + 4

Put it altogether:

5² - (3² + 4)

5² = 5 * 5 = 25 and 3² = 3 * 3 = 9, so:

25 - (9 + 4) = 25 - (13) = 12

The answer is thus 12.

Answer:

Step-by-step explanation:

Find the length of the leg(s) of a right triangle, to the nearest hundredth, if both legs are equal and the hypotenuse is 10.

charle [14.2K]

Answer:

7.07 units

Step-by-step explanation:

Use the Pythagorean theorem for the right triangle:

$\text{hypotenuse}^2=\text{leg}_1^2+\text{leg}_2^2,\\ \\c^2=a^2+b^2.$

If a = x, b = x, and c = 10, then

$10^2=x^2+x^2,\\ \\100=2x^2,\\ \\x^2=50,\\ \\x=\sqrt{50}=5\sqrt{2}\approx 7.07\ units.$
