An isosceles triangle has two sides of equal length. The third side is five less than twice the length of one of the other sides
4vir4ik [10]

Answer:

9

Step-by-step explanation:

We can set up a systems of equations to find the value of the third side.

Let's assume that x is the length of both sides 1 and 2. Let's also assume that y is the length of the third side.

We know that x + x + y = 23, and looking at the first clue we can make the equation y = 2x-5.

We can substitute y into the equation x + x + y = 23.

x + x + (2x-5) = 23\\\\2x + 2x-5 = 23\\4x-5 = 23\\4x = 28\\x = 7

So the length of the side that is the same as the second is 7.

Now we can plug this into the equation y = 2x-5 to find y.

y = 2(7) - 5\\\\y = 14-5\\\\y = 9

Hope this helped!

Can you guys help me?
denis-greek [22]
Pretty sure you have to use the Pythagorean Theorem.
a^2+b^2=c^2

So you would plug in your numbers that you already have (6 and 10) But notice that 10 is the hypotenuse (longest side) so
6^2+x=10^2

Then you would solve it and you should end up with 11.6619
