On a right triangle, to find one missing side you can use this equation
a^2 + b^2 = c^2

a and b are the sides next to the right angle, and c is the hypotenuse (side not connected to right angle).

You first need to find the length of the dotted line before finding x. This is because to be able to use the above formula, you have to know the length of two out of three of the sides.

To solve the length of the dotted line, note that it also makes a triangle with the 5 unit line and the 5 √5 unit line. You can plug these numbers into the formula.
(5)^2+b^2=(5 √5)^2
25+b^2=125
b^2=100
b=10

Now that you know the length of the dotted line is 10 units, you can now solve for x

(20)^2+(10)^2=x^2
400+100=x^2
500=x^2
x= √500, which equals 22.361

if the measurements given are 333333 and 656565 then to find the diagonal length. we can use the Pythagorean theorem.
333333^2 + 656565^2 = x
take the square root of 333333^2 + 656565^2 to get 736334.49

The least amount of wrapping paper needed to wrap a cube-shaped gift is 150 square inches. How long is one side of the gift?
devlian [24]


Isn't the only thing you have to do is since a cube has 6 sides than you would have to do 150 divided by 6. If I am correct.
