Answer:

<h2>h = 18 cm</h2>

Step-by-step explanation:

A=\dfrac{bh}{2}\\\\A=117\ cm^2\\b=13\ cm

Substitute:

117=\dfrac{13h}{2}               <em>multiply both sides by 2</em>

234=13h            <em>divide both sides by 13</em>

18=h\to h=18\ cm

Lena [83]
1) The set of words represented in the first task is definitely ''<span>member and class '' type of analogy. That's pretty easy, it reminds of definitions  : simile is one of type of the figurative language and </span><span>isosceles is one of the types of triangles.

2) What about the next set, I am pretty sure that the gap should be filled with </span>jaywalking : offense :: bottle : container. I think that these words represent consequences, so jaywalking soneer or later will be spotted and it would have become an offence, and bottle will spent the rest of its life in the container.

If the square root of 61 is the longest side length in the triangle and the shorter sides are x and x+1, find the value of x tha
Tju [1.3M]

Answer:

  x = 5

Step-by-step explanation:

You want to find x such that ...

  x^2 +(x +1)^2 = 61

  2x^2 +2x -60 = 0 . . . . . simplify, subtract 61

  x^2 +x -30 = 0 . . . . . . . divide by 2

  (x +6)(x -5) = 0 . . . . . . . . factor; solutions will make the factors be zero.

The relevant solution is x = 5.
