You can divide both 12 and 9 by 3 so 9 would be 3 and 12 would be 4 so the answer is 3/4

Two poles of lengths 10 ft and 15 ft are set up vertically with their bases on horizontal ground 12 ft apart. Find the distance

Maru [420]

When we connect the ends of the poles and the project the horizontal line from the end of the 10-ft pole to the other pole, we form a right triangle with the legs equal to 12 ft and difference of the lengths of the pole. Using the Pythagorean theorem,
h² = sqrt ((12 ft)² + (15 - 10)²)
h = 13 ft
Thus, the distance between the tops of the poles is equal to 13 ft.

The length of the longer leg of a right triangle is 6 cm more than twice the length of the shorter leg. The length of the hypote

iragen [17]

Let x = the shorter leg
2x + 6 is the longer leg
2x + 9 is the hypotenuse

We now do the Pythagorean Theorem of $a^{2}+b^{2} = c^{2}$

$x^{2} + (2x+6)^{2} = (2x+9)^{2}$

Multiply out to get:

$x^{2} +4 x^{2} +24x+36=4 x^{2} +36x+81$

The $4 x^{2}$ will cancel out each other when you combine like terms to get all the terms on one side of the equal sign.

Combine like terms with the rest to end with $x^{2} -12x-45=0$

Factor this to get $(x-15)(x+3) = 0$ then set each factor equal to zero.

You end up with two solutions, x = 15 and x = - 3 HOWEVER distance cannot be measure in negatives so that answer will not work so x = 15. Now plug into our given information.

The short leg is 15 cm long.
The longer leg of 2(15) + 6 = 36 cm long
The hypotenuse of 2(15) + 9 = 39 cm long.

You can check your answers by plugging them into the Pythagorean Theorem again.
