To the nearest tenth, what is the length of the hypotenuse of an isosceles right triangle with a leg of 7 square root 3 inches?
Morgarella [4.7K]
If it's a right triangle, and is also an isosceles triangle, namely two sides are of equal length, that means the other non-right-angles are 45° each, so the triangle is a 45-45-90 triangle, and thus we can apply the 45-45-90 rule, so let's do so.  Check the picture below.

Find the sum 6y sqrt a +7y sqrt a
Rom4ik [11]

For this case we must add the terms of the following expression:

6y  \sqrt {a} + 7y \sqrt {a}

It is noted that the terms are similar, so we can add:

We take common factor \sqrt {a}:

\sqrt {a} (6y + 7y) =

We add the terms within the parenthesis:

\sqrt {a} (13y) =

finally we have:

13y \sqrt {a}

Answer:

13y \sqrt {a}
